At least 17 people found dead in S. African nightclub

At least 17 people have been found dead in a nightclub in South Africa's East London city, local media report.

Bodies were found at the Enyobeni Tavern early on Sunday, and reports say several people were injured.

"The circumstances surrounding the incident are under investigation as we speak," a police spokesman told the Newzroom Africa television channel.

"We do not want to make any speculations at this stage," Brigadier Tembinkosi Kinana said.

A large number of emergency service personnel are on the scene in the Eastern Cape province.

Relatives of the victims have been unable to see their bodies, reports say, and locals have called for the venue to be closed.

Eastern Cape Police Commissioner Nomthetheleli Lilian Mene told SABC News that "there was an alleged stampede inside the tavern".

The BBC has been unable to verify this and details are still emerging.

Four people have been taken to hospital, SABC reports.

Brigadier Kinana told reporters most of those found dead were young adults aged between 18 and 20.

Eyewitnesses told the Daily Dispatch newspaper that bodies were lying inside the venue as if they had collapsed on the floor.

A spokesperson for Eastern Cape's health department told News24 the dead bodies were taken to various nearby mortuaries.

Siyanda Manana added: "We are going to conduct autopsies as soon as possible to establish the probable cause of death."
