Only so much the police can do

Cambridge Police report on an incident Saturday:

On 1/17/09 at 12:41 AM, units responded to Mass Ave. and Sidney St. for a disturbance on an MBTA bus. After further investigation it was learned that an attempted robbery occurred. Four suspects were stopped but the victim refused to cooperate.

The following day, however, there was plenty for police to do over at the CambridgeSide Galleria, where they arrested a woman charged with stealing from a mall cart - after she allegedly tried to bite an officer.
