A Radford University professor arrested twice in the last month faces new charges.
Last Thursday, March 21, officers arrested Taj Mahon-Haft on 24 counts of possession of child pornography.
Police now say Haft faces nine charges for production of child pornography.
The charges stem from computers investigators took from his Radford home back in December.
Police say while serving arrest warrants at his home earlier this evening, Haft resisted arrest and is also being charged with assaulting a police officer.
He's being held in jail tonight without bond. The investigation is ongoing.
Back on March 13, Haft was arrested and charged with possession of bath salts and marijuana.
