Police are searching for two suspects who robbed the Hualai Chinese restaurant near 51st and Walnut early Monday morning, according to reports. The incident took place at around 1 a.m. when the suspects entered the restaurant, forced the owners – a husband and wife –  to the back of the restaurant, and pistol-whipped both of them. The suspects took an undisclosed amount of cash and fled in a black car.

The restaurant owners were taken to the hospital and are listed in stable condition, CBS Philly reports. No more details and no surveillance video are available at this time. We’ll update when we have more information.
