Chicago police are investigating a vehicle that crashed into the downtown studio of WLS-TV (ABC-7) during the top of last night's evening news, causing no injuries.

Just after 10 p.m., a loud noise was heard inside the studio and on the air, startling weekend anchor Ravi Baichwal.

A police spokesman, Officer David Banks, said early this morning that the investigation was only in its early stages.

Banks said it was not immediately clear why the male driver of a Mazda MPV with Indiana license plates plowed into the studio's reinforced glass wall.

ABC 7 President and General Manager Emily Barr said the incident might have been deliberate, but there was no way of verifying that late last night.
