CCTV footage showing a group of men attacking an American student with a bottle just days after he arrived in London has been released by the Met police.
Francesco Hounye, 22, from Florida, required more than 23 stitches after his face was slashed with glass near Brick Lane in Tower Hamlets on 17 June. He also chipped a tooth and said he is now too scared to go out in London alone.
Police want to trace five Asian male suspects who are believed to be in their late teens or early 20s.
