Houston police searching for suspect who attacked technician at ATM

Police say a technician was attacked while servicing an ATM in southwest Houston

It happened a month ago on Bellaire near Hillcroft. 

The technician told police a man tried accessing the open ATM, so he grabbed him and wrestled with him until he said he had a gun. 

The tech then backed off and the man ran away.

It's unclear if he got away with money. 

If you know who the suspect is, call police.
