Argument, shots fired outside a coney island overnight on Detroit's west side

(FOX 2) - Detroit police are investigating a shooting outside of a coney island restaurant on the city's west side. 

An employee at a nearby gas station tells us he heard arguing and then gunshots, and that the restaurant was full of customers at the time including small children. 

It happened around 1:45 a.m. Tuesday at the Super Coney Island in the 14000  block of Wyoming, near Lyndon. We're told police arrested a 32-year-old man and seized a gun. 

"First thing, I heard two gunshots, and then five minutes later it was kind of quiet and then it started going again. A lot of gunshots, and people running and stuff," says Mohamed Hassouneh who works at a nearby gas station. 

Nobody was injured, although multiple shell casings were found in the parking lot.
