Hamilton residents are being advised to check their home security following a series of intruder incidents in the east of the city on Sunday.
The first incident happened about 3am when a woman asleep with her partner in their Hillcrest Rd home woke to find a male holding her hand.
"The intruder fled when the woman screamed," said Detective Sergeant Kristine Clarke of the Hamilton CIB.
"A short time later, about 3.20am a man arriving home at his Orelio St property was confronted by a man inside his house who pointed a gun at him before fleeing the scene."
A young woman staying with a friend in the University of Waikato Halls of Residence complex on Silverdale Rd woke up about 4.15am to find a man bending over her female friend who was sleeping in an adjacent bed, Ms Clarke said.
