Police say that after an unsuccessful robbery, Matthew Peverada threatened a South Portland store clerk that he would return at 11 p.m.

Police were waiting for him when he came back, arresting him on charges of robbery, criminal threatening and criminal mischief.

Peverada allegedly went to Dipietro's Market on Cottage Road Saturday afternoon and brandished a knife demanding money from the cash drawer. When he was denied, he left but vowed to return.

He came back at 4:30 p.m. and tried to throw a planter through the window, but it bounced back, police said. He then said he would return at 11 p.m.

Just before then, police patrolling the area on the lookout for Peverada stopped a car he was in and arrested him on charges of criminal threatening, criminal mischief and robbery.

Police say Peverada does not appear to have any connection to the store, but had been asking for a person with the same first name as another person who works there.
