Iranian singer Dariush's concert in London was canceled after bomb threats were made and the venue was evacuated. No explosive devices were found at the Eventim Apollo in Hammersmith and police were called to the scene.
Videos on social media showed people outside the venue chanting "one solution, revolution" - an obvious reference to the ongoing protests in Iran over the death of 22-year-old Mahsa Amini. A Met Police spokesman said: "There is nothing to suggest that the threats made were genuine, but at 8.21pm, officers attended the venue to speak with security staff and to determine if they were aware of anything suspicious or concerning.
"None of the suspicions came to the attention of staff, but at around 8:40 p.m., the venue management took the decision to evacuate as a precaution."
"There were no reports of injuries and no suspicious items were found," they added.
Amini's death in police custody has sparked widespread protests in Iran that have been met with a government crackdown, including the beating, arrest and killing of demonstrators.
