The men have forced their way into homes near the 12000 block of Dunblane Avenue in Porter Ranch.
Police say the two incidents happened two weeks ago in broad daylight. In each case, the house was ransacked and the suspects stole jewelry.
"The suspects in these cases are reportedly targeting jewelry," said LAPD Det. Matthew Phelps. "The reason being the high prices of gold these days, it's an easy turnaround for them."
According to authorities, they were supposed to be burglaries. However one turned into a home invasion when a resident ended up being inside the home.
"They went in a location where they were confronted by an individual who was inside one of the residences," said Los Angeles Police Capt. Kris Pitcher. "They ultimately tied the individual up, they ransacked the house and left."
No one inside the homes was injured. Police said the suspects were not armed.
A home security camera caught images of one suspect and a white Chevrolet Traverse SUV believed to be the getaway vehicle. Authorities said the vehicle has damage on the front passenger door.
The suspects are described as African-American males between 20 to 25 years old. One is 6 feet 3 inches tall and around 210 pounds; another suspect is described as 5 feet 9 inches tall and around 180 pounds. There isn't a description of the third suspect.
Police said the number of burglaries in the Porter Ranch, Northridge, and Granada Hills areas has spiked in the last month, but a home invasion hasn't happened in two years.
