Portland's acting chief of police issued a statement after learning an officer allegedly refused to help during an armed robbery.
The statement from Chief of Police Larry O'Dea read in part, "When the Police Bureau became aware of this allegation, we immediately opened an internal affairs investigation.
"When a community member asks for our help, especially in dangerous situations, I expect Portland police officers to do all they can to help. I am certain this is a community expectation as well ... I am sorry that this did not happen in this case and the internal affairs investigation will determine why."
O'Dea went on to thank the witness who came forward to report the matter, which happened on July 26 near Central Drugs on SW Fourth Avenue and SW Alder Street.
Police said Jocelin Olson held up the downtown drug store and workers there ended up chasing him down and holding him until officers arrived.
A witness later reported that he ran out of the store and told a police officer about the holdup but claimed the officer wouldn't respond because he was off duty.
The officer in question has come forward.
The police bureau said it will not be releasing his name.
