Indiana authorities are searching for a 16-year-old boy in connection with the shooting of five teenagers at a downtown canal in Indianapolis Saturday night. 

Police Chief Paul Ciesielski of the Indianapolis Metropolitan Police Department said Monday that investigators have identified the 16-year-old as a person of interest, Fox affiliate WXIN-TV reported.

Ciesielski said the victims and several witnesses have implicated the teenager in the crime, but he said the boy has not been named a suspect, according to the station.

Five teenagers were injured during the shooting at the downtown canal at around 10 p.m. Saturday. Three of the teenagers were treated and released, while two of the victims remain in serious condition -- one with a leg wound and the other with a bullet wound to the chest. 

Police said the shootings occurred following an altercation between two groups of teens, the station reported. 

"The biggest problem, I believe, is unsupervised children. Again, from all ages," said Ciesielski. "We see kids even younger than 14 out in the middle of the night, unsupervised," Ciesielski told WXIN. 

Early Sunday morning, a SWAT team with the Indianapolis Metropolitan Police Department raided an Indianapolis home, searching for evidence. Ciesielski said nothing was found in the home.
