Portland police charged a man with theft after he allegedly grabbed a store clerk’s money bag Wednesday morning.

An employee of Shipwreck & Cargo was in front of the store at 207 Commercial St. with a deposit bag about 9:25 a.m. when a man grabbed the bag and ran, said Lt. James Sweatt.

The case was originally reported as a robbery but police determined that the thief did not use force or threaten the worker and so was charged with theft.

However, when a suspect was located at 1 Portland Square, police arrested him at gunpoint because of the robbery allegation, Sweatt said.

The man’s name was not released, he said, because the case is still being investigated and police were considering using a lineup to identify him.
