Police patrols have been stepped up following an increase in burglaries of student homes in Sheffield.
South Yorkshire Police said a number of 'sneak-in' burglaries have been reported in student accommodation in Norfolk Park over recent days.
A force spokesman said: "PCSOs and police officers are increasing their patrols in the area to try and prevent further offences and to catch those responsible.
"Spread the word, make sure your doors and windows are locked - even when you are home.
"These offences take opportunists only seconds to commit. Don't make it easy. "
The force also wants to hear about people selling stolen property.
Call South Yorkshire Police on 101.
