Counter terrorism officers are looking for several witnesses to the deadly attack on a Manchester synagogue to come forward.
Jihad Al-Shamie, 35, drove his car into worshippers at Heaton Park Hebrew Congregation Synagogue in Crumpsall before attacking them with a knife on 2 October.
Melvin Cravitz, 66, and 53-year-old Adrian Daulby were killed while Al-Shamie was shot dead by police.
Detectives said they were yet to speak to an elderly man with a distinctive wide-brimmed brown hat, walking with a young child, who was recorded on CCTV close to the scene moments before Al-Shamie attacked.
