More than 30 serious criminals have been jailed after UK police cracked their encrypted text messages and uncovered a violent feud over stolen drugs.

Crime bosses in the Huyton Firm, had planned to murder the men they thought had taken more than £1m of cocaine from them.

After a successful challenge in court, BBC Panorama obtained 10,000 of the firm's messages.

They reveal plans for brutal violence, including a handgrenade attack.

The Huyton Firm named after the part of Merseyside where it is based has been run for 30 years by two secretive brothers.
