A Boston man was arrested Friday morning, Feb. 27 by Belmont police – with a big assist from the department’s K9 officer, Grim – for allegedly selling heroin in Belmont.

The arrest of Harrison Soto-Zuazo, 34, of Jamaica Plain, came after Belmont police received complaints from resident of street-level drug deals being conducted in town, according to the Belmont Police.

Belmont Police Det. Michael Pugliese, along with members of the Suburban Middlesex County Drug Task Force, conducted a investigation that led to a search warrant being issued for Soto-Zuazo’s motor vehicle.

At 11:43 a.m. Friday, detectives observed Soto-Zuazo operating his vehicle on Pleasant Street. After stopping Soto-Zuazo’s vehicle and not finding any illegal narcotics, detectives called Belmont Police K9 Officer Corey Taylor and Grim. The K9 officer performed a search of the vehicle and Taylor reported to the detectives that Grim had given an indication that there were narcotics in the rear portion of the center console. Examining the console closer, detectives discovered an aftermarket modification that revealed a “hide” inside the vehicle. Inside detectives discovered 68 grams of heroin.

Soto-Zuazo was charged with trafficking in heroin, furnishing a false name, refusing to identify himself, use of a false RMV document and operating on a suspended license.
