An assistant teacher at a King Open Extended Day, an afterschool program at the King Open school, has been arrested on a child rape charge, school officials said Friday.

The arrest was made at a private home and the suspect, identified as Chris Bradshaw, 24, has been removed from his position at the school, said Superintendent Jeffrey Young and King Principal Tim Groves. The suspect was arrested Wednesday night and arraigned Thursday.

Cambridge District Court Judge Michelle Hogan ordered Bradshaw held on $5,000 cash bail with the conditions that he has no contact with the victim or the victim’s family, no contact with any witnesses, no unsupervised contact with children under 16, no employment or volunteer work with children and must report to the probation office once a week.

Bradshaw must return to court is May 7 for a probable cause hearing.

“These are troubling allegations against a man who we allege took advantage of, and sexually assaulted the young vulnerable victim.” District Attorney Gerry Leone said in a press release. “Compounding the troubling nature of the allegations is the fact that the defendant, until this incident was reported, worked directly with young children.”

According to the press release:

According to authorities, on April 1, the victim’s mother was having a birthday party at her house for a friend. The defendant was a guest at the party and a friend of the victim’s mother. While the adults were upstairs, the defendant went downstairs to watch television with the victim, age 9, and his sister. Around 11 p.m., the victim’s sister went upstairs to go to bed, leaving her brother asleep on a couch and the defendant watching television on another couch. Approximately 30 minutes later, the victim’s sister got up and went downstairs where she allegedly witnessed the defendant sexually assaulting her brother.

Upon further investigation, which included interviews with witnesses at the scene, the defendant was arrested and charged with rape of a child.

Anyone with pertinent information is asked to call police at (617) 340-3300 or the child abuse unit of the Middlesex District Attorney’s Office at (781) 897-8400.

There will be a community meeting at 6 p.m. Monday at the school’s library with a counselor who can answer questions about the impact the arrest might have on children and how to talk to children about sexual assault.

The prosecutor assigned to the case is Assistant District Attorney Katharine Folger, chief of the Child Abuse Unit. The victim witness advocate is Nicole St. Pierre, and the child interview specialist is Katie Nugent.
