A murder investigation has been launched after a 25-year-old man was shot dead in a suspected gang attack outside a London pub last night. Emergency services raced to The Landor pub in Clapham at around 10pm, where they found a man suffering from gunshot wounds. Witnesses describe hearing three gunshots outside the pub while terrified residents said they heard loud 'bangs'. A police forensics tent remained in place across the road from The Landor pub on Tuesday and a bouquet of flowers had been placed near its entrance. Last year, a 27-year-old man was shot dead on New Park Road in Clapham.
