Police said Vadim Spitsyn, 52, a driver for the St. Petersburg Interior Ministry, brought the homemade explosive to the police office in St. Petersburg in January and detonated it in a corner of the front porch, RIA Novosti reported Friday.
The investigators said the device only partially exploded and Spitsyn hid behind a door to evade injury, but he feigned being injured and told police "an unidentified person" set off the bomb.
Police said Spitsyn claimed to have suffered headaches, loss of consciousness, nausea, and neck and shoulder pain as a result of the explosion.
Investigators said Spitsyn orchestrated the incident "to raise his credibility in the eyes of his associates and colleagues."
Police said Spitsyn is facing charges of giving false testimony and misleading information, attempted fraud, trafficking explosives and disorderly conduct.
