According to a foreign news agency, Nick Anderson was at the eatery girlfriend when a robbery took place. Anderson got hold of the mugger as he ran towards the door.
The eye-witnesses stated that Anderson locked the robber in a choke hold when he started demanding money from the cashier.
An off-duty cop, who was at the crime-scene, assisted Anderson to hold the suspect till the authorities arrived at the scene.
Authorities added that the suspect matched the description of a man who had looted the same eating-spot twice.
Anderson proposed her later that night and she said yes.
