Police have released a picture of Manchester bomber Salman Abedi, taken just days before the attack which left 22 people dead.
Abedi is seen wheeling a blue suitcase in the picture, which police hope will prompt members of the public to come forward with further information.
Officers believe the suitcase in the picture is not the same one Abedi used during his attack on Manchester Arena last Monday evening.
Greater Manchester Police have made a string of arrests over the past week, mainly focusing on the south Manchester area, as authorities search for anyone who may have had links with Abedi.
Although Abedi acted alone at the scene of the attack, it is believed he was part of a wider network and Home Secretary Amber Rudd has suggested some members of that network may still be at large.
