Police are hunting these suspects, some of whom are wanted for questioning over serious crimes such as rape and murder.
West Midlands Police have published pictures and details of suspects they are after.
They include Walikhan Sultan-Khal who officers say is wanted for questioning on suspicion of human trafficking and rape, and Marius-Lonut Lordin who is wanted for questioning over a sexual assault.
Police are still trying to locate a key suspect in connection with the murder of Mansoor Mahmood.
The murder inquiry was launched in October last year after the 24-year-old was stabbed to death and found outside Dixi Chicken diner in Brierley Hill.
Detectives named Niron Parker-Lee as the key suspect in November and urged the public not to approach him if spotted.
Detective inspector, Harry Harrison said: “Someone knows where this man is and I’d remind them that harbouring a wanted man is a criminal offence and you may also face prosecution.”
Anybody with information is urged to contact police immediately on 999 quoting reference 78/16/DY.
If you have information about any of the other criminals in the video above you should call Police on 101 or contact Crimestoppers anonymously on 0800 555 111.
