Shootings in three college communities over the weekend left one person dead and at least 21 others injured.

Indiana, Delaware and Alabama police are each investigating shootings in crowded parties near college communities, according to police and university statements.

Seven were hospitalized in Bloomington, Indiana, near Indiana University's homecoming, while the University of Delaware is still counting victims (six are reportedly hospitalized) and the Magic City Classic football game between Alabama A&M and Alabama State near Legion Field in Birmingham, Alabama, left at least one dead and eight wounded.

After midnight near Indiana University, officers monitoring a large crowd around Kirkwood Avenue and Dunn Street heard shots around 1:30 a.m. ET and saw a man with a firearm running from the area, Bloomington police said.

Officers took the man into custody near Dunn Meadow, and recovered a gun and shell casings in the area. Police said it remains unclear whether the suspect fired any shots. No deaths were reported in Bloomington, and police said they did not know whether there were additional victims.

A disturbance in the crowd may have preceded the shooting, police said. Indiana University police and Indiana State Police assisted in the response. In Newark, Delaware, a shooting on Saturday night rocked the University of Delaware.

"We are deeply concerned about the shooting on Main Street Saturday night, which has impacted our entire community," the school's director of media relations Peter Bothum told Fox News Digital in a statement. "We are grateful to the Newark Police Department, which is leading the investigation. Wee will continue to communicate confirmed information, which will be shared on a dedicated alerts page (and updated as we learn more." University President Laura Carlson said victims were receiving care and thanked Newark police, campus police and other first responders for providing on-scene care.

"I am writing to you about the shooting last night in Newark on Main Street, although it is difficult to know what to say when violence like this erupts in our community," she wrote in an email to the school community.

"We are all impacted," she continued. "I ask that you keep the victims in your thoughts and hearts as they receive care. Please also recognize the impact and toll on our students and community members who were on Main Street last night and witnessed this violence." The university did not provide a confirmed number of victims or say whether anyone had died, but a report indicated at least six were hospitalized. The investigation is being led by Newark police. The school urged students and staff to follow its campus alerts page for confirmed updates.

In Birmingham, Alabama, one person was killed and eight others were wounded Saturday night after the Magic City Classic football game near Legion Field, police said. Officers found nine people with gunshot wounds in the 400 block of Graymont Avenue West shortly after 7:50 p.m. ET. One victim was in critical condition and seven others were stable, authorities said.

Michael Pickett, chief of the Birmingham Police Department, said most spectators and families had left the stadium property after the game, but the shooting happened nearby, where vendors were set up along Graymont Avenue.

He said he was "very grateful that more people weren’t injured." Police spokesperson De'Rell Freeman said one person had been detained and transported to police headquarters for questioning, and "multiple weapons" had been found and secured.

Alabama State and Alabama A&M are historically Black universities and archrivals whose annual contest has been played for more than 100 years. Nearly 70,000 fans attended Saturday's game, won by Alabama A&M 31-28. The event draws some of the largest crowds in the country for games played in their college football division.

The Magic City Classic has such a deep history that Alabama State coach Eddie Robinson Jr., a former NFL linebacker and alumnus of the school, proposed creating a Hall of Fame for the game.

In addition to the shootings near campuses, police in Dallas say four people are dead and 15 are injured following three separate shootings in a Dallas neighborhood. Police Chief Daniel Comeaux said police are still trying to determine if the shootings were related or what led to them. Comeaux said some arrests were made but he did not specify how many or what charges were involved.

"This is a really big scene. It's spread out," Comeaux said. "We are interviewing some individuals right now that we have arrested, still trying to figure out exactly how it ties into all the shootings out here." In Fayetteville, Arkansas, six people were taken to hospitals with gunshot wounds from a shooting that happened early Sunday. No arrests have been made, police said in a news release. A preliminary investigation indicates an altercation preceded the shooting.
