It looks like a knockout.
Police asked for help Wednesday identifying a man who punched a weather station sensor April 9.
Authorities released a surveillance video of the man, who can be seen walking up to the sensor in the 2600 block of West Oak St. on the night of April 9.
The man who appears to be talking on a cell phone, then punches the sensor while almost losing his balance.
Anyone with information should call Denton police.
