A security guard working at Westfield Stratford City was issued with a warning after it was found he was working without the correct licence.

Four other workers at stores within the centre were also warned by Security Industry Authority (SIA) inspectors for failing to display their licence or failing to tell of a change of address.

Forty-five premises at Westfield Stratford City were visited on November 17. Out of the 52 people checked, 51 were correctly licensed.

SIA investigators are now speaking to the security companies involved, individual stores and security management teams at the shopping centre.

The checks were carried out to make sure that door supervisors, security guards, CCTV operators were working legally by holding a valid SIA licence and obeying licence conditions.

At the Stratford Centre, six premises were visited. All 12 workers checked held the correct licence for their role.

But at one store in the centre, a man was found working with a door supervision licence that was not valid for the CCTV duties he was undertaking.

The SIA said it would be speaking to the security supplier that deployed him.

SIA head of investigation, Darren Woodhouse, said the fact that Newham is one of the main Olympic host boroughs meant further enforcement work will be carried out.

He added: “Licensed security operatives can help play an important role in ensuring the safety of businesses, local people and tourists.”
