The FBI is now involved in a string of armed robberies in Portland, and has released an enhanced compilation video of the suspect.

At the end of the video, officials are asking for the public's help identifying the suspect, but emphasize the need for caution. The man is considered armed and very dangerous, so should not be approached by anyone other than law enforcement. Portland Police have said they believe he's 'desperate' and badly in need of money. If cornered, it's unpredictable how he will react.

The images on the compilation video highlight things like brand of sneakers and logos on jackets worn by the suspect during the robberies. Police have not definitively said they believe it's the same man committing all the crimes, but they do say the armed robberies are related. The suspect descriptions from the 9 robberies are very similar, of a white man with blue eyes and light-colored hair, who stands between 5'5" and 5'7".

A list of robbery locations and dates appears at the end of the video. Anyone who thinks they may have information that could help in the investigation is encouraged to contact Portland Police at (207) 874-8575.
