Dump truck rams TV station in Maryland, armed person might be inside

A vehicle has rammed a television station and police say there may be an armed person inside the building.

In a tweet, station WMAR-TV identified the vehicle as a dump truck.

According to ABC2 News reporter Brian Kuebler; "Suspect tried to get in building screaming LET ME IN and said he was into a landscaping truck and rammed the building like 3 times. I saw last 3 as he broke through into lobby."

A hole the size of several garage doors could be seen in the front of the building Tuesday afternoon.

A nearby school has been locked down as a precaution.
