A bouncer was suspended following a row which escalated outside 54 nightclub in Liverpool city centre.
Merseyside Police confirmed they are investigating the incident and had been invited to examine the CCTV of the footage by club staff, which 54 also released to the ECHO. According to a statement from 54 nightclub, police officers told them they "felt the actions of the door-staff were justified".
The club did, however, accept that the doorman was "overly aggressive" in his response to the incident. The Security Industry Authority (SIA), which regulates licences to work in the security industry, confirmed it is also investigating the incident.
