Dump truck driver crashes vehicle through the security gate of the FBI's offices in Pittsburgh.

A dump truck driver from Ohio has crashed his vehicle through the security gate of the FBI's offices in Pittsburgh, injuring himself but no one else.

Special Agent Gregory Heeb says the truck was moving erratically and running through stop signs and red lights, promoting Pittsburgh police to pull it over around 11 a.m. Tuesday. Heeb says the driver told police he wanted to ram the gate, sped away and then smashed into the gate.

The truck was disabled by security barriers that are meant to prevent vehicles from driving into the office complex on the city's South Side.

FBI agents checked the truck for bombs and found nothing.

Heeb says the FBI is working with police to determine charges. The man's name wasn't immediately released.
