PUPILS hosted a surprise visit by police sniffer dog Zam when he visited an East Yorkshire school.

The three-year-old black Labrador, who is trained to hunt for drugs, was led on a tour of the toilets and grounds of Goole High School as part of a police visit, aimed at advising the students on how to “stay safe”.

While he did not find anything, staff said the exercise provided an example to students of tactics that could be used in the school’s zero tolerance approach to drugs, as well as what could happen while they were on a night out.

PC Mike Simpson, of Goole police, gave a talk to the students about behaving responsibly.

He said: “I urge pupils to be sensible when drinking and also not to accept anything from anyone they don’t know.”

The message was re-iterated by assistant head teacher John Niland, who told students: “Don’t let people lead you astray.”

PC Simpson said the police had a good relationship with the school and would be carrying out a follow-up visit for a talk about sexual health.
