2 ARRESTED IN INVASION ROBBERY.

Byline: Lisa Van Proyen Daily News Staff Writer

Responding to a 911 call, police arrested two suspects Wednesday soon after four armed robbers invaded a home in Pacoima.

After tying up a man with electrical cords and covering his head with a cloth, one of the robbers warned him: ``Don't call the police or we'll kill you,'' the victim told officers of the Los Angeles Police Department.

Detective Bob Brophy of the LAPD's Foothill Division said that after the robbers left, the man broke loose from the cords and got a description of their car.

He called 911, alerting officers in the area, who found the car matching the description within 10 minutes, said Detective Sue Allison of the LAPD's Valley Bureau.

``It was excellent work,'' Brophy said about actions of the robbery victim. ``It was excellent police work, too.''

Paul Huette, 20, of Sylmar and Hugo Alvarado, 26, of Panorama City were arrested on suspicion of committing a home-invasion robbery, police said.

Two other suspects got away, Brophy said.

At about 1 a.m. Wednesday, two women knocked on the victim's door in the 13200 block of Filmore Street, Brophy said.

The resident, in his 30s, came to the door, and the women said their car ran out of gas and asked him for help.

The man stepped out of his home and saw two men. Brophy said the victim told police that one of two men pointed a shotgun at his head and said, ``I'll blast you.''

The second male robber put a hand over the victim's mouth, pushed him into the home, tied him up and threw apparel over his head, police said. One of the robbers kept his foot on the victim while others ransacked the home.

The two men suspected of being the male robbers were being held at the Foothill Division jail in lieu of $50,000 bail each.

Detectives were searching Wednesday for the two female suspects, described as 18 to 20 years old.
