Two people were arrested during a gang-related homicide investigation in North Hills Thursday morning, officials said.
The FBI SWAT team entered a home in the San Fernando Valley neighborhood using flash bangs, FBI spokeswoman Laura Eimiller told KTLA.
Residents of a property with several homes were awoken about 5 a.m. by what they thought were gunshots. More than 10 residents were lined up against a wall, searched and questioned during the investigation.
"We heard a loud bang," said resident Edwin Mendosa. "And then ... they came on the speaker and asked for everyone to come out of the house."
No shots were fired during the incident and two people were taken into custody.
The Los Angeles Police Department officials tweeted Thursday that the FBI SWAT officers helped the gang task force serve a warrant for a homicide suspect.
A woman who described herself as being the mother of two brothers who were arrested told KTLA that as officials searched through her home, she and her daughter were crying and they did not understand what was happening.
Another resident, 14-year-old Ruby Garcia, said she was grabbed by an officer who told her to put her hands up, and police eventually handcuffed her mother.
"They told us to go in the back and everyone who lives here, they put them in handcuffs," she said.
When authorities first approached the home, Garcia said she and her mother thought they were someone else and took cover.
"My mom was so scared that we went to the floor and put a blanket over us," she said. "And then I told my mom that we should call the cops."
No further details about the incident or investigation have been released.
