Singer Selena Gomez has reportedly been urged by the police to lock the doors of her house after she complained of an intruder.

The police has given Gomez a reminder following the 22-year-old star's complaint last week, reports tmz.com.

According to law enforcement sources, the `Come And Get It` hitmaker raised the alarm after she returned home to find a door unlocked. However, the police had found nobody inside. This is said to be the third time that Gomez has contacted the police over fears that her house had been broken into, and for it to be a false alarm.

Earlier this year, Gomez had gates put up around the house after a stalker allegedly showed up at her $3 million property.
