BRITISH Transport Police (BTP) are trying to track down these men in connection with a spate of bike thefts at Bromsgrove Station.
Some have been forcibly taken and at times cutters have been used to break locks.
Following investigations and CCTV enquiries officers now believe the ten thefts are linked.
Officers believe these men may have information which could help the investigation.
Anyone who knows who they are should text the BTP on 61016 or call 0800 40 50 40.
Alternatively, call Crimestoppers on 0800 555 111.
Police said bikes remained popular targets for thieves and officers urged cyclists to use strong, durable locks when securing their bikes at stations.
Cyclists are also urged to register their bike at www.bikeregister.com so if bikes are stolen they can be returned if they are recovered.
