Police were out in force in York at the weekend in an operation to tackle knife and drug crime.
Officers, some with police dogs, took to the streets in the city centre for Operation Search.
A North Yorkshire Police spokesperson said: “Operation Search uses a variety of different police resources including high and low visibility officers and the dog support unit.
“This is a proactive police response, which aims to target knife carriers and drug users in the night time economy.
“We were inside popular venues and outside your favourite nightclubs with drug dogs and supporting venues by providing them with knife wands for the evening.”
