The Night Tube has been up and running since August 19 and with over 750,000 passengers using the service, there have been just 31 crimes recorded by British Transport Police.

The 24-hour service currently runs on three lines, the Central, Victoria and the Jubilee line. The latter launched only recently, on October 9. The Northern line and the Piccadilly line will follow later on this year.

Despite there currently being only a handful of incidents recorded, concern has been raised over whether incidents could rise in the future.

Arinite Health and Safety has compared London's Night Tube to Berlin's 24-hour underground network. The service, which opened in 2003 saw a spike in offences some years after its initial set-up in 2012, with 1,044 offences recorded, in comparison to its earlier years, with 673 recorded in 2008.

The Berliner Verkehrsbetriebe (BVG) responded to concerns by installing more video equipment and emergency call points.

Bryan Richards, managing partner of Arinite, said not all risks are foreseeable: "There are inherent safety and health risks which cannot be eliminated. For example, passengers falling or being pushed onto the line. The relatively new Jubilee line recognised this potential hazard by installing an extra platform barrier, eliminating the risk.

"For other lines, the risk remains and if there are more people under the influence of alcohol using the Night Tube, could such risks increase?"

Satir, who works on the Central line, told Arinite that the service will be great for the city, but he added: "I can see there being issues, possible with drunk people. Because it runs so late, it opens up the opportunity for things to happen."

Transport for London's Director of Enforcement and On-Street Operations, Steve Burton has reassured passengers, telling getwestlondon : “The Tube network is a safe, low-crime environment with very few people ever experiencing or witnessing crime.

“All stations that are open through the night are staffed at all times and by working extremely closely with British Transport Police passengers see as many BTP officers out on patrol overnight as they do during the day.”

An extra £3.4 million is being spent by TfL to ensure the Night Tube is policed. Currently there are over 100 BTP officers patrolling the Night Tube at any one time.

“The launch of Night Tube was a very significant event for the London Underground and a special moment in history for London." said Chief Superintendent Martin Fry of British Transport Police. "We will continue to deliver the exceptional service that the people of London have come to expect. Our priority will always be the safety and security of passengers and staff traveling and working in London.”
