A pickpocket who stole from fans during a System of a Down gig has been jailed for four months after he was tracked down by a "find my phone" app.
Leonard Dragomir, 40, took phones from fans attending the performance at Wembley Arena where the American rock band played in April.
Several fans reported thefts to security guards after the gig. The Evening Standard reported that police used the phone-tracking app to trace one of the smartphones, which had been left on.
They found Dragomir with the stolen electronics in Walthamstow, north-east London.
Det Const Rob Borgeaud said: "I hope this sentence serve as a warning to others that we will disrupt organised criminal networks and ensure they are brought to justice."
System of a Down have been touring after almost a decade of inactivity, reuniting during that time but failing to release an album.
In an interview with Rolling Stone in January 2015, frontman Serj Tankian said the band may consider recording a new album after they complete their Wake Up The Souls tour.
