SALEM, Mass. (WHDH) -- A Salem police lieutenant, accused of sexually assaulting a woman in his home, turned himself in to police Tuesday.

Matthew Desmond, 41, was arraigned on Tuesday -- the same day he marked 15 years with the Salem police department. Desmond is now on paid administrative leave after a woman accused him of sexual assault last month.

The woman said she was at Desmond’s house watching her children and his children play while Desmond and his wife were at work. The woman said when Desmond returned home she was on the couch and he swiped her breasts with his hand and put his hand up her dress telling her to “stop being a tease.”

She said Desmond then said, “Come on, come on” as if to suggest they should do something more. As he left, she said he said, “Next time, don’t wear underwear.” She replied, “Stay the [blank] away from me.”

A man at the Desmond house declined to speak Tuesday afternoon and Desmond’s attorney denied the allegations.

“He’s adamant about the fact as I said in court today that any contact between him and the complaining witness was initiated by the complaining witness with her obviously full knowledge and initiation and consent,” said Desmond’s attorney.

Salem police said they were fair and thorough with their investigation into the allegations.

“At least on some level I think it should give the citizens some comfort that we call it as fair and thorough as we can and I think that’s what was done here,” said the Salem police chief.

Desmond posted bail, which was set at $5,000.
