TEXAS (CNN) -- Surveillance video showing a robbery in progress in Midlothian, Texas was released Tuesday. The incident happened last month when police say 19-year-old Dylan Bearden tried to rob an Exon Station.

Video shows Bearden coming in and pushing Daniel Gaskey aside before pulling out a knife and demanding money. Gaskey, an off-duty Mansfield firefighter who also served in the Marines, decided to take matters into his own hands.

He grabbed Bearden from behind, put one arm across his chest and with the other grabbed the knife in his hand and threw him to the floor
