The Ritz Ybor in Tampa was evacuated after police received a prank call about a shooting inside the venue. 

Officials said they responded to the nightclub, located on Seventh Avenue in Ybor City, after someone called 911 to report that people were being shot inside.

When police arrived at the scene, they checked the building but did not find any weapons.  No one was injured.

An estimated 1,000 concertgoers waited outside while police investigated the threat.  Those people have since been allowed back inside the building.

The concertgoers were at the club to see the Summer Slaughter Tour, featuring Cannibal Corpse, which was scheduled for 1:30 p.m.
