Police are appealing for information following a robbery at a Stivichall newsagent's.
A man walked into Dawlish News on Dawlish Drive just before 10pm on Tuesday, 23 April, before threatening staff with a hammer.
The employees managed to fight the suspect off before he fled the scene empty handed, leaving behind the hammer and a bike (pictured).
Officers are trying to establish whether the bike is stolen or belongs to the offender.
Anyone who has information relating to the incident, or recognises the bike, is asked to contact West Midlands Police via Live Chat between 8am and midnight, or call 101 anytime quoting crime number 20CV/97428H/19.
