Emergency calls for police to attend Kingston superclub Pryzm dropped 45 per cent in two years, figures have revealed, just a day before a council review of the nightclub's licence.

Kingston police asked for a review of the licence—which could see it revoked or altered with conditions—after what officers said was a series of crimes over the Christmas and New Year period.

The club's manager told Kingston Council he was disappointed by the licence review request because of a drop in both violence and theft.

Licensing officer PC James Hartland said in a statement that logs had been improperly completed and some incidents, including an alleged sexual assault, were not reported to police.

Data released by the Metropolitan Police today under the Freedom of Information Act shows that in 2013 police received 92 999 calls to the club, which was renamed Pryzm from Oceana that autumn.

In July 2013 two men were found guilty of stabbing clubber Jamie Sanderson to death in October of the previous year.

Club manager Dan Corry was praised by police for his "tact and professionalism" on the night.

The club's licence, held by Luminar, previously Deltic Group, was revoked in November 2012 but restored with conditions some months later after a private meeting.

Today's figures show that in 2014 the number of 999 calls dropped to 60, and then to 51 in 2015. Between January 1 and May 31 this year, 14 emergency calls were made.

Reports of violence against a person dropped from a total of 44 in 2013 to just five in the first five months of this year.

Mr Corry, six years in post as manager, has submitted a statement to Kingston Council in advance of tomorrow's review in which he says that, when he requested details of the four holiday-season incidents cited by PC Hartland, "I did not receive any further details".

The victim of the alleged sexual assault told club staff she did not want to involve the police but the situation ought to have been escalated to a senior manager, Mr Corry said.

He said that the incident log, which is separate from a log of people ejected from the club, is completed by a manager, rather than individual bouncers, to ensure consistency and readability.

He added: "This has been the procedure for as long as I can remember.

"It was the procedure we used at the time of the review in 2012, and has never until now been questioned or criticised by police.

"I have been advised by the police that I should only involve the police if an incident is not serious where the victim wishes to press charges."

In his extensive statement Mr Corry added: "With the level of violent incidents having significantly reduced since January, and theft being at its lowest I can recall, I must express my disappointment at the timing of the review application brought by the police.

"We have implemented the measures we said we would in February and this has seen a reduction in crime which were were convinced we would see.

"I do not therefore understand which the review application was brought.

"If the police wish to change their requirements that is their prerogative but, from a management perspective, we appreciate clarity and consistency."

The review hearing will be held at Guildhall tomorrow from 10.30am.
