PROVIDENCE, R.I. (WJAR) — Providence police said four juveniles are accused of assaulting a 51-year-old man on Monday.

According to police, they responded to 249 Manton Ave. for a report of an assault.

Witnesses told police that several people assaulted a man, knocked him to the ground, repeatedly kicked and punched him.

They then fled the area, according to officials.

Providence police said the victim was taken to Rhode Island Hospital.

"In the early morning hours of Jan. 20, detectives were notified that the victim’s condition had significantly deteriorated," a Providence police spokesperson said.

According to officials, three juveniles were taken into custody later that day for a separate disturbance. Police said they were caught throwing rocks at cars.

Police said the three admitted to being involved with the assault of the 51-year-old man during an interview.

A fourth juvenile was apprehended Tuesday night.

Providence police said the four juveniles -- three 12-year-olds and an 11-year-old -- were charged with felony assault and conspiracy.

Authorities said they will also face additional charges stemming from the later disturbance.

"I think that's crazy because what is a 12-year-old doing having these kinds of behaviors?" one neighbor said. "I think there should be more question asked. I think teachers need to be paying more attention. I think parents, mostly need to be paying more attention."

The juveniles are being held at the Rhode Island Training School.

"I think just, keep an eye on our children, make sure they're okay, make sure they're doing good and encourage them to do the right thing and to be someone better," one neighbor said.

The victim remains in serious condition with life-threatening injuries, Providence police said.
