A Boston cleric and former public high school employee already facing an attempted murder charge for allegedly shooting a 17-year-old student in the head has pleaded not guilty to gun and drug charges.

A judge Tuesday bumped bail for the Rev. Shaun Harrison by $150,000 to a total of $400,000 following his arraignment on two counts of unlawful possession of a firearm and single counts of trafficking in cocaine, and other charges.

The gun and drug charges came after a search of the 55-year-old Harrison's home. Police found two guns and drugs in a safe in his basement.

His lawyer said "a number of people" had access to the safe.

Authorities say he was involved in the drug trade.

Harrison has been fired from his job at English High School.
