Police have located the man they believe sexually assaulted a young woman at the Brookline Public Library over the weekend.

Tyler Grace, 29, is being held in Penobscot County Jail in Maine on charges that are unrelated, but similar, to those he faces in Brookline, according to a release put out by the Brookline Police Department on Wednesday, May 4.

According to Mass Most Wanted, a website maintained by the Metropolitan Law Enforcement Council, the reportedly sat next to the victim, masturbated to something on his laptop computer, then stood and ejaculated on the victim.

Grace, for whom no permanent address was available, will be arraigned on his Maine charges at Penobscot County Courthouse on Friday, May 6, the statement said. Police are unsure when he will be sent back to Brookline to face charges of open and gross conduct, indecent assault and batter and assault and battery with a dangerous weapon (bodily fluids).

Grace was identified with the help of video surveillance footage taken from the Main Branch of the library, according to the statement.

“Diligent, professional work by members of the Brookline Police Department Detective Division, lead to the location of this subject,” police said.

Library Director Chuck Flaherty said Saturday’s incident was “more disturbing” than any other incident he’s had to deal with in his 38-year career. The assault took place at a table in the Brookline Room, and there were at least three patrons within 20 feet of the suspect, he said.

Flaherty said the library was cooperating with police and the media in order to get the suspect’s description and image out and bring him in. He also said patrons should not be afraid to come to Brookline’s libraries.

“I think libraries are safe, but we are open to everyone. There’s no type of TSA check taking place at our door to keep out the bad guys. This type of incident is rare, but it’s very unfortunate,” Flaherty said. “While I certainly wish it didn’t happen, libraries are safe, and I don’t think people should be concerned about their safety when they come to the library.”

The act and the suspect were captured on surveillance video, but the images are “of poor quality,” police said.

Flaherty said the cameras are eight or nine years old, and were probably not “cutting edge” technology when they were new.

“Unfortunately, this incident tells me we need to look at upgrading the cameras to get better technology,” Flaherty said.
