Police Dog Sniffs Out Evidence in Alleged Knife Assault

A Medford police dog found a knife in some bushes on Main Street believed to have been used in an assault Sunday night.

Police were called to Main Street in South Medford about 9 p.m. Sunday, where there was reportedly an attack on the street involving a knife, according to a police report. 

The two men involved knew each other and were in an argument over money when the dispute got physical, the report said. One of the men involved told police he ripped his shirt off, and then ran when the other man allegedly pulled out a knife.

The man suspected of pulling the knife, Shane Tresilian, 37, of Malden, was located near 330 Main Street and stopped and questioned by police.

Meanwhile, Marco, a police K-9, sniffed out the torn up t-shirt and a knife, which was hidden in bushes outside Dello Russo Funeral Home on Main Street, said the report, written by patrolmen Thomas Fazio. Tresilian was arrested and charged with assault and battery with a dangerous weapon after the knife was found, the report said.

His arraignment was continued Monday in Somerville District Court, where he was ordered held on $1,000 cash bail.
