'TOILET TORCHER' REWARD OFFERED !

The mystery attackers have targeted toilets across San Francisco

A US firm is offering $5,000 (£3,450) for clues leading to the arrest of an arsonist who has been setting portable toilets on fire across San Francisco.

The Clorox Company is also offering a year's supply of toilet cleaning products in exchange for such tips.

More than two dozen toilets on San Francisco construction sites have been set on fire in the city in recent months, the Associated Press reports.

The cost of the damage has been estimated at $50,000.

The Clorox Company is sending out a team to advertise its offer to locals.

The patrol service is "a crappy job, but somebody's got to do it", joked a company spokesman.
