Monday, July 30

• Operating to endanger – Raymond Arroyo, 20, listed as homeless. Officers were watching Boylston Street at Fisher Avenue, when they saw a vehicle they estimated was going about 70 mph at around 1:45 a.m.--the radar gun showed it was going 87 mph. When police switched on their sirens to pull the car over, it turned quickly onto Chestnut Hill Avenue without signaling. The vehicle turned onto Channing Road, seemingly trying to elude police. Police brought him to a stop on Channing, and spoke to the driver. Arroyo has an active learner's permit, and he was driving a vehicle rented by one of his passengers. He was arrested and charged with operating to endanger, failing to stop for police, and two counts of speeding. 
• Assault-and-battery with a dangerous weapon – 49-year-old Chandler Purvis of Amory Street. At around 11:45 a.m. on Monday, a woman called police saying that a man had flicked a cigarette at her, in what she said was a completely unprovoked attack. She says she had seen him before, and that he had spat on her on two previous occasions, once while she was walking in the park with her daughter. Police arrested Purvis, who the witness identified, and charged him with assault-and-battery with a dangerous weapon and two counts of assault.

Thursday, Aug. 2

• Unarmed robbery – Luis Montanez, 30, and Benny Montanez, 22, both of Dorchester. Just after midnight on Thursday morning, a witness contacted police, saying she was awoken by a woman screaming at two men. Police spoke with a woman who told them two men had taken her phone and fled. Shortly afterward, police arrested and charged two men with unarmed robbery. According to a Brookline Police Blog post, the woman described the subjects as one clean-shaven Hispanic male in his early- to mid-twenties, with a flat-brimmed hat, short black hair; the other was also a Hispanic male in a black hat. The two got into a black vehicle after the incident, reported at 12:05 a.m. Shortly afterward, 12:55 a.m., police say they saw a black vehicle with no front plates driving into Brookline from Brighton, and noted that the passengers matched the victim's description from earlier. When officers ran the plates, they found that the plates matched another car. Police pulled the two men over, found a cell phone like the one stolen from the woman on Washington Street near Corey Road. The woman positively identified the two men, and police arrested and charged them with unarmed robbery.
• Malicious damage of property – Roslindale woman, Ariel O'Reilly, aged 26. A witness saw someone get out of her car and key the passenger's side of a nearby vehicle parked on Harvard Street before 11 a.m. Police determined that the woman had been fired by her employer at about 10:30 a.m., and that the vandalized vehicle belonged to her former employer. Police issued a warrant to charge her with malicious damage.
