PORTLAND — Another candidate has joined the race for mayor.

Hamza Haadoow, a Somali immigrant with deep community ties, announced today in a press release he will seek the office this fall.

Haadoow, former owner of BNS Transportation and Jubba Halal Market, co-founded both the East Africa Family Association and Somali Community Development of Maine.

Candidates can’t start circulating petitions to get on the ballot until July 1. Once they register, however, they can set up candidate committees and raise funds. Ballot petitions require at least 300 signatures by Aug. 29.

Haadoow has scheduled a news conference for 10:30 a.m. Tuesday at City Hall in the State of Maine Room.

Haadoow joins a list of 12 others who have already filled out candidate registration forms. They include Mayor Nick Mavodones, City Councilor Jill Duson, Eric Bennett, Zouhair Bouzara, Charles Bragdon, Michael Brennan, Markos Miller, Peter Bryant, Jodie Lapchick, City Councilor David Marshall, Jed Rathband and Christopher Vail.
