DRINKERS in pubs and clubs across Middlesbrough town centre came under investigation from a drug-busting sniffer dog.

Over the weekend, officers from Cleveland Police and the British Transport Police targeted revellers who they suspected were in possession of drugs.

Inspector Gary Gamesby, head of Middlesbrough police operational support unit, said: "This was about deterring dealers targeting revellers in the town centre, but also sending out a message that we will not tolerate drug abuse in our pubs and clubs.

"We have worked with the British Transport Police before. This is a partnership approach which lets criminals know that all resources available will be used in the fight against drugs and crime."

In total, out of 30 people who were searched, nine were detained and three were released on police bail. Six were cautioned for unlawful possession of controlled drugs including cannabis, amphetamine and cocaine.

Four revellers were arrested for public order offences.

Insp Gamesby said: "This operation undoubtedly helped prevent drugs getting into pubs and clubs.

"It sends a strong signal to those minded to deal in illegal substances that police are always on the watch and ready to act."
