OKLAHOMA CITY (AP) _ Federal authorities are asking the public to help them track down a man accused of robbing four Oklahoma City banks since February. The FBI is offering a $3,000 reward for information leading to the arrest of Jan Michael Phillips, who's been charged with the May 7th robbery of Chase Bank on North May Boulevard. The Oklahoma Banker's Association is offering an additional $2,000 reward.


FBI spokesman Gary Johnson says authorities are concerned about escalating violence in each of the robberies.


He says the 25-year-old Phillips wielded a gun during the Chase Bank robbery.


Phillips was last seen driving a silver 2004 Chevrolet Colorado pickup with Oklahoma tag number 547-XSZ.
