Door supervisor Found Guilty
A Cardiff man is the first person to be found guilty of committing an
offence under Section 19 of the Private Security Industry Act 2001 –
intentionally obstructing any person in the exercise of Security
Industry Authority (SIA) business.
On Monday 10 October 2005 at Cardiff Magistrates, doorman Dustin Pitman
was found guilty of two offences: obstructing an SIA Official and
working without holding an SIA licence. Pitman was fined £200 and given
a conditional discharge.
On 13 March 2005, officers from South Wales Police were conducting
checks on door staff at Bar Risa in the city centre. When asked, Pitman
could not produce a door supervisor licence, he gave false information
to the police and attempted to leave the venue.
Sue Sheath, SIA Head of Investigation for Wales said:
"Door Supervisors play an important role in ensuring a safe night out
in Cardiff and it is vital they are professionally trained and
qualified. Those Door Supervisors who persist in working without a
licence put themselves at risk of prosecution, and this conviction
demonstrates that unlicensed activity will not be tolerated. We work
closely with South Wales Police to ensure that there is compliance with
the legislation and commend their efforts in bringing this case to
trial."
