(CNN) -- A man in Baltimore, Maryland, charged with attempted murder escaped from police custody and is believed to be on the move, possibly as far away as Washington or West Virginia, police said Saturday.
Paul Bryan Palmer, a suspect charged with attempted murder for an August stabbing, broke free on Friday while being transported to the city's central booking facility.
"It is believed that Palmer fabricated a medical injury in an effort to elude arrest. Palmer was able to break free from hand restraints and escaped from the city's downtown police district," police said.
Palmer -- last seen wearing a black ball cap, a sleeveless muscle T-shirt, and brown work boots -- might be traveling with a female companion in a silver 2008 Kia Spectra with a Maryland tag of 1EWB10.
The vehicle is using a " donut"-type tire as one of the spare tires.
Police said Palmer "should be considered dangerous," and advised anyone with information into his whereabouts to call 911 immediately.
