A man was stabbed and is under arrest after trying to rob a South Philadelphia sushi restaurant Thursday afternoon.



Authorities say that just before 3 p.m. an armed 19-year-old man -- whose mom identified him as Tishon Jones -- tried to rob the Terryin Sushi Bar on the 300-block of Synder Avenue at gunpoint, but a restaurant employee decided to make matters into his own hands.



The restaurant's owner, Ryan Zheng, told NBC10 that he struggled with Jones before an employee grabbed a sushi knife and stabbed the would-be robber in the back twice, stopping the suspect in his tracks, according to police.



The owner's wife and young son were inside the restaurant, watching the scary struggle.



"We're fine. Everything feels alright and police got the guy," said Zheng.



Today's incident would have been the third time the sushi bar was robbed in less than three weeks and police say Jones is the man responsible.



They also say he is behind the robberies of three other businesses, including a neighborhood grocery store and a pizzeria.



The Lyn Grocery Store on South 4th Street was robbed on November 30. The suspect got away with $50. Two days later, South View Pizza was hit. $500 was taken from the register.



Detectives are on the scene interviewing Terryin's owner and witnesses. The suspect was transported to Methodist Hospital after the stabbing before being moved to Jefferson where he remained in stable condition.
