Visitors to Saturday's 90s-themed party in the village of Burgsinn were promised a night of fun and games, reports Süddeutsche Zeitung.

However, the party came to an abrupt halt when a man began filling the air with pepper spray – leaving at least 11 people with painful eye injuries.

According to police, those injured in the attack were taken to hospital for treatment before giving witness statements.

However, confusion about the night's events was rife – and the victims' accounts were far from conclusive.

Police initially narrowed the search down to two suspects – and announced on Sunday evening that a 21-year-old man was being questioned over the assault.

Witnesses were unable to say whether the man intentionally sprayed the gas, or the canister simply burst due to the heat in his hand.

Some witnesses reported that the man appeared to be drunk.                                                     

Police are continuing to investigate the incident.
