Braintree police are on the lookout for those behind the theft of seven catch basin covers over the last two nights.
The basins, square sewer grates that weigh 90 pounds each, were stolen Tuesday and Wednesday night from Old Elm Street, Hayward Street and Commercial Street, Chief of Staff and Operations Peter Morin said.
Police are looking for adjacent surveillance cameras and the town is in the process of replacing the grates, which cost approximately $200 a piece. Morin said the thieves will probably me able to get $20 per cover based on the metal weight.
Morin encouraged residents to call 911 if they hear unusual noises in the street at night, and if they see a missing basin to call the DPW at 781-794-8950.
The uncovered holes lead to a three to four foot drop that can be hazardous to motorists, bicyclists and pets, Morin said.
