For the second time in two weeks, Somerville police busted a heroin dealer in Davis Square in response to citizen and business complaints about drug activity in the square’s busy plaza, Statue Park.

Angela Pisani was arrested July 20 in the Davis Square train station after drug unit detectives learned that “a white heavyset female about five feet tall wearing a blue shirt, named Angela would walk down Meacham Road and sell heroin,” police said.

On July 16, a Somerville man was arrested in the area after investigators allegedly saw him make a hand to hand drug deal and found heroin in his pocket.

Pisani was arrested after she allegedly tried to swallow bags of heroin as Somerville Police detective James approached her.

When Hyde placed his finger in her mouth to retrieve the drugs, Pisani allegedly bit down on his finger and “thrashed about” in the station, police said. She allegedly spit up one bag of heroin.

Pisani, 38, of 190 Beach St., Malden, was arrested and charged with resisting arrest, assault and battery on a police officer, drug violation near a school or park, witness intimidation and possession of a class B drug with intent to distribute.
