London police are warning students to keep their doors and windows locked after receiving five reports of apartment break and enters in under a week.

These break-ins all happened between March 2 and March 8 around Saunby Street near Western Road—an area known to be off-campus student housing.

The break-ins happened between 8:40 p.m. and 2:15 a.m.

The intruders gained entrance through basement windows and bedrooms, police say.
