SAN DIEGO -- Police are stepping up patrols in North County, where folks are worried they could wake up to a gun in their face.
It's happened already at several homes up and down the I-15 corridor.
In all of the cases -- there are five so far -- three masked men have entered a home through an unlocked door, tied up their victims and then ransacked their belongings. No one has been hurt, but it's certainly a frightening experience.
Investigators believe it's the same three men responsible for each break-in.
- Friday, Jan. 29 -- A Scripps Ranch family is tied up and held at gunpoint by three suspects who ransack their home.
- Sunday, Jan. 31 -- Burglars rob a home in Sorrento Valley.
- Friday, Feb. 5 -- Three men break into a home in Rancho Bernardo . They tie up two residents with shoestrings and flee with cash and jewelry.
- Thursday, Feb. 11 -- Around 2:30 a.m., burglars enter a home in Sabre Springs while a family of four is sleeping. The homeowner, his wife and their two children were not hurt.
- Thursday, Feb. 11 - Around 5:20 a.m., dispatchers receive a 911 call about three suspects who had broken into a home in Carmel Mountain , approximately five miles from the home in Sabre Springs.
Police have received no clear suspect descriptions in any of the cases. The male suspects are always nondescript, dressed in black and have their faces covered with masks and bandanas.
