At least five people were wounded during a shooting at a San Antonio, Texas, flea market on Sunday, according to police

Iran Press/America: Police Chief William McManus said gunfire erupted about 11:30 a.m. at Mission Market during a dispute on the ground.

“This is the result of some type of argument. I don’t know if the argument was between gang members or just people who knew each other or didn’t know each other,” McManus said.

One of the five is critically injured.

The chief said a security guard also opened fire, but it was not known if the guard is among the five people wounded, the AP reported. 

The manager of the flea market, Al Ramon, told the newswire the argument did not involve any market employees. 

“It was between a vendor and buyer, or two vendors, we don’t know exactly,” Ramon said.

McManus said two weapons were recovered at the scene but the number of gunshots fired was not immediately known.
