Jared Remy, the son of Red Sox broadcaster Jerry Remy, allegedly assaulted another inmate at the Middlesex County Jail where he awaits trial on charges of killing his girlfriend in August, the Middlesex sheriff's office said Friday night.
Remy, 35, of Waltham, was charged with assault and battery with a dangerous weapon Thursday, the sheriff’s office said. The inmate Remy allegedly assaulted was a fellow pretrial detainee at the jail in Cambridge.
Remy is slated to be arraigned on the new charge April 24 in Cambridge District Court. He was moved to an isolated area of the jail after the alleged assault, according to the statement.
A spokesman for the sheriff’s office would not give further details on the episode Friday night.
Remy is awaiting trial on a count of murder and five other charges in the killing of his girlfriend, Jennifer Martel, 27, on Aug. 15. His trial is scheduled for October.
Martel left behind the couple’s daughter, Arianna, who turned 5 shortly after her mother was killed.
The Middlesex district attorney’s office has come under scrutiny for allowing Remy to return to the apartment where he and Martel’s resided, after the assault. In December, District Attorney Marian T. Ryan ordered a review of the office’s handling of the case.
Prosecutors said after the killing that Remy attacked Martel in their kitchen, living room, and on a stairway before pinning her to the ground of the patio, where he stabbed her repeatedly, in the view of several neighbors.
At least one neighbor in the Windsor Village apartment complex tried to pull the burly Remy off Martel, but was driven back when Remy began trying to strike him with the knife, Assistant Middlesex District Attorney Lisa McGovern said at the time.
“Great force and great effort was made by this defendant in stabbing Ms. Martel over and over and over again,’’ McGovern said, in what she called a “protracted struggle.”
In court, McGovern said that when Waltham police arrived after numerous 911 calls, Remy was shirtless and his socks were stained with Martel’s blood. He held his hands over his head and surrendered to the officers without incident.
Their daughter was at home during the attack, said Ryan, the district attorney, who added that the girl is now in the custody of the state Department of Children and Families.
