VERGENNES — Vergennes police twice last week issued no-trespass orders on a man they and city business owners believe was using Main Street business restrooms to do drugs.

But, police said, they couldn’t prove the man had done so, although in both instances he stayed in the restrooms for long periods of time and showed clear signs of being under the influence.

The first call came from Champlain Farms on May 17. Employees said the man had entered the store restroom more than once that day. Police said they found a syringe in the restroom, but couldn’t prove who’d left it there.

On May 21, they issued him the second no-trespass order after being alerted by Three Squares Café employees of a similar situation.

Between May 17 and 23, Vergennes police conducted one foot and nine cruiser patrols, two property watches and two VIN inspections, responded to one false 911 call, and:

On May 17, responded to New Haven Road argument between a grandmother and granddaughter that centered on the younger woman’s boyfriend.
