Confidential security documents for an Olympic Games training venue, Mayesbrook Park in Dagenham, have been found dumped in a bin by a Walthamstow resident.

The paperwork contains detailed drawings of security cameras and building layouts for a sports hall at the Mayesbrook Park complex in Dagenham, which was designed to provide a safe training environment for 800 sportsmen and women during the Games.

Walthamstow resident Ron Daniels contacted the Waltham Forest Guardian after he made the "stunning" discovery last week at his workplace in Smithfields Meat Market in Farringdon.

"I noticed them sticking out of a rubbish bin and when I had a closer look I couldn't believe it," the 62-year-old said.

"The documents show every room, every camera, the wires they are connected to and everything. If it got into the wrong hands it could be very dangerous.

"It's disgusting to find this sort of thing - whoever threw them away should have shredded it."

The four large maps, seen by the Guardian, are titled "security layout" and are dated July 2011.

A LOCOG spokeswoman said: "These plans are not the security plans for the Mayesbrook Park Games-time training venue.

"They are plans from a mechanical electrical contractor to do with possible installation of CCTV cameras.

"This contractor has not been used by LOCOG for its Games time arrangements. There has been no security breach."

The paperwork is marked with the logo of Briggs and Forrester, a building services company which was involved in the construction of the sports hall.

The firm has a London office about half a mile away from the meat market in City Road, but it is unclear who may have dumped the documents as several firms and organisations have been involved in the project.

The Mayesbrook Park complex, in Lodge Avenue, includes the newly-opened £8million multi-use sports hall, said to be the largest in the country, along with several temporary venues. Large sections of the park have been fenced off and closed to the public for eight weeks so the athletes can reportedly "train in safety".

Among the sportsmen and women using the site are Olympic Handball, Paralympic Judo, and Wheelchair Rugby teams.

The athletics arena also hosts Olympic and Paralympic Athletics training, and the southern area of the park is reportedly for Olympic and Paralympic throwing events training.

When Barking and Dagenham Council approved the plans back in February, council documents said security at the site was a high priority.

They stated: "In order to provide adequate security for the Games it is proposed that the entire site be fenced off during the training period.

"This would involve the erection of a 2.7m high mesh fence...[and] within this area a number of temporary tents and cabins would be erected in order to meet operational requirements to provide facilities such as offices, toilets, and security at the site entrance."

Mr Daniels, of Douglas Avenue, added: “I've worked at the meat market for over 40 years and I've never seen anything like this.

“With all this worry and focus on security you would think they would be a little more careful.”

The Guardian has contacted Briggs and Forrester for a comment, but is yet to receive a response.
