Cambridge Police Department Arrest Suspect on Multiple Warrants Following Indecent Assault

Detectives with the Cambridge Police Department have arrested Andrew Ma, 39, of 97 Arnold Street in Braintree, on multiple warrants out of Cambridge District Court in connection with an indecent assault that occurred on August 20.

Ma was arrested and charged with Open and Gross Lewdness, Indecent Assault & Battery, and Assault and Battery.   Warrants were issued for him after a Cambridge resident attempted to fix her bicycle on Cambridge Street Wednesday, August 20 at approximately 11:20 p.m. and was approached by Ma, who was driving his black SUV. Ma asked if she needed any assistance, she stated she didn’t, and walked away with her bike.  Shortly thereafter, Ma came back and pulled in front of the woman. After asking if she had change for a $20, Ma reportedly grabbed the victim by her left wrist, touched her indecently and asked her for a sexual favor. He then pulled down his shorts while in the motor vehicle, exposed himself and then began to perform a sexual act on himself.  The victim fled from Ma and rode her bicycle to her residence, where she subsequently reported the incident to the police. 

The details contained above are allegations.  The suspect is presumed to be innocent unless and until proven guilty beyond a reasonable doubt in a court of law.
