EMERYVILLE (KTVU) -- Authorities said Thursday that a five-alarm fire that broke out last month along the Emeryville-Oakland border was deliberately set and officials are asking for help identifying a suspect.

The Bureau of Alcohol, Tobacco Firearms and Explosives announced a $100,000 reward in connection with fires on May 13, 2017 and July 6, 2016 at a development located in the 3800 block of San Pablo Avenue, just off of Interstate 580.

The development at the site includes a six-story apartment complex that is under construction. 

During the press conference, officials released images from surveillance cameras which captured the suspect wearing a black hooded jacket who was on a bicycle.  Authorities said the suspect canvassed the property before the blaze began.

Authorities said they have identified only one suspect in the May 13 fire while last year's blaze is still under construction.

No injuries were reported from either fire.

Anyone with information was asked to call the ATF at 888-283-3473.
