Vladimir Mehul Baptiste, 28, of Parkville, Md., was arrested late Tuesday. He was sent to a hospital for a psychiatric evaluation and charged with attempted murder.
Holed up in an editing suite at WMAR-TV's building in Towson, just outside Baltimore, Baptiste communicated with the outside world by Twitter.
One communication read:
YOU DONT HAVE TO WORRY ABOUT ME RIGHT NOW, THE PEOPLE YOU ALL HAVE HURT ARE GOING TO DEAL WITH YOU! WATCH— Vladimir M. Baptiste (@VlaDziuBaptiste) May 13, 2014
In a later tweet, he said:
Body Hosting my people to make them do and say things, that's truly not from their hearts....JUST WAIIIIIIT!— Vladimir M. Baptiste (@VlaDziuBaptiste) May 13, 2014
Security guards at the station said they heard loud knocks on the door just before noon Tuesday. A few minutes later, a truck hit the building.
The truck had been stolen from a landscaping company that had a job nearby.
Station employees were able to get out of the building safely, and no injuries were reported. Most gathered in a parking lot where they also used social media to tell the story.
WMAR, the ABC affiliate in Baltimore, was unable to broadcast during the standoff.
Baptiste was being held in lieu of $750,000 bail and faces a long list of charges.
