INDIANAPOLIS — Two women and three children have been wounded in a shooting inside an Indianapolis townhome, police said Monday.

Authorities said no one has been arrested and that police are looking for three suspects in the Sunday night attack.

Lt. Richard Riddle of the Indianapolis Metropolitan Police Department said police were called to the home on the city’s northwest side at 9:25 p.m. Sunday. He said two women were shot along with two children and an infant.

All were hospitalized in serious condition, police said. Authorities have not released the victims’ identities or the relationship between them.

A police statement early Monday said authorities were seeking three suspects who fled the complex in a vehicle after the attack, but that a motive was unclear.

“This does not seem to be a random act of violence, and the detectives believe the parties involved knew each other,” the statement said.

Detectives are canvassing the townhome complex for witnesses and information. Riddle said earlier that a man who wasn’t hit by gunfire had witnessed the shooting.
