By all accounts it was a massive operation: heavily armed policers homed in on the club and received the support of a police helicopter. The Brusselsesteenweg was closed to all traffic during the operation that hadn't been planned in advance and was a response to a telephone call. Cars using the Gentbrugge motorway slip road were diverted.
Fortunately, the police operation had been completed by 12:30 AM. A number of individuals were led away for questioning. As yet police have been unwilling to comment on what exactly happened.
