A Plano, Texas Police Department bomb disposal team was sent to Borderlands developer Gearbox’s headquarters yesterday to deal with a car bomb threat, according to a series of tweets from Gearbox President Randy Pitchford.

Pitchford said that the the police arrived around 7:30 p.m. CST, after most Gearbox employees had already gone home. As you can see in the picture in Pitchford’s tweet below, the police used a bomb disposal robot, apparently to clear one of the cars in the building’s parking lot. It didn’t find anything.

“I witnessed many police cars, the bomb disposal unit’s bus, the robot and several BDU and PPD personnel working,” Pitchford said. “I (foolishly) was not worried (choosing to believe the threat not credible), but Plano PD was pro, all business and kept everyone safe!”

Pitchford said the police wouldn’t disclose any details about the threat and at the moment it’s not clear if the it had anything to do with Gearbox, or if it was aimed at one of the other companies that are also in the developer’s building.

In August, a hacker group that said it caused a PlayStation Network outage claimed responsibility for a bomb threat that grounded a plane carrying Sony Online Entertainment president John Smedley. The group has been active since, most recently taking responsibility for downing Activision games Destiny and Call of Duty: Ghosts. However, both the group’s website and Twitter account have been taken down earlier this week.
