(CNN) -- A Detroit man, who stabbed an officer outside a courtroom and escaped wearing the officer's uniform, has been captured, authorities said. The inmate, Abraham Pearson, was spotted walking in a Detroit neighborhood Monday night, said Wayne County Sheriff Benny Napoleon. Authorities said Pearson attacked a deputy with a sharpened comb in front of two other inmates inside a holding cell at the Frank Murphy Hall Monday morning. He then handcuffed Deputy Harrison Tolliver, and fled, also taking the officer's cell phone and radio, the Wayne County Sheriff's Office said. The two inmates did not intervene or leave the cell, according to police. Pearson escaped from the rear of the building, carjacked a citizen and drove away in a Dodge minivan. The Dodge was recovered and the officer's uniform was found under a vehicle near Beaubien Street in Detroit. Pearson was facing sentencing on Monday on carjacking and armed robbery charges. According to the sheriff's office, the 25-year old has a lengthy criminal record and was on parole. The arrest could add at least 11 more charges to the crimes he was already facing, Napoleon said. Tolliver, 63, was taken to the Detroit Receiving Hospital and later released. Tolliver is a retired Detroit police officer who joined the Sheriff's Office in December.
