Portland police are investigating a theft at a restaurant under construction on Free Street in which stereo equipment and tools were stolen.

The theft was reported at 8:15 a.m. by contractors working at Rhum, a tiki bar being developed at 4 Free St. by Jason Loring, owner of Slab and Nosh Kitchen Bar.

Workers had last been at the site at noon on Sunday and had locked it, police said. On Monday morning, they found someone had forced the door open and stolen tools, including power saws and drills, and stereo equipment for the business. The total value of the theft is about $5,000, police said.

Tools are often targets for theft because they can be sold relatively easily online or pawned, police said.

Loring posted on his Facebook page that all his contractor’s tools and $3,600 in stereo equipment was stolen.

Police asked that anyone with information about the theft call 874-8575.
