Parts were removed from cars parked in two downtown lots last week during the day.

Officers responded to a report of a suspicious person working under a vehicle parked in the lot behind Darien Sport Shop, 1127 Post Road, around 2 p.m. Thursday, Sept. 20. The caller told police there was a white Nissan Altima occupied by three black men next to the car on which the suspicious person was working.

An officer and the owner of the 2006 Honda CRV on which the person was spotted working discovered that the catalytic converter, worth about $1,200, had been removed. Police said it appeared a power tool was used to remove the part, but no further evidence was recovered.

Around 6:30 p.m. Sept. 20 police were called to the parking lot behind the Post Office at 30 Corbin Drive. The owner of a 2008 Honda CRV told officers he parked around 7 a.m., went to work, and heard a loud noise when he started his car to leave. The owner looked underneath and found that the catalytic converter, worth about $1,200, had been removed.
