Three people were arrested in connection with a hostage takeover at Nordstrom Rack in Westchester, an LAPD source said.
The suspects, whose identities were not immediately available, were arrested since after the Friday incident.
Police are expected to announce details about the arrests at a press conference on Monday.
One person was sexually assaulted and another was stabbed in the neck during a hostage situation at a Southern California shopping center that ended early Friday after Los Angeles Police Department SWAT members entered a Nordstrom Rack and escorted at least 14 people from the building.
Gunmen at the Promenade at Howard Hughes Center in Westchester held the hostages in a storage area before the early morning operation, police said.
Police received a 911 call about the hostage situation before 11 p.m. Thursday when a man said his girlfriend saw two armed men enter the store.
The store was closed at the time an officer witnessed a man exit the store, then run back inside after he noticed the officer. Authorities said they are investigating whether the assailants might have posed as customers and remained in the store after it closed at 10 p.m.
At about midnight, officers had surrounded the Nordstrom Rack, which is on the second floor of the Promenade. At about 2 a.m., SWAT members found 13 women and one man -- employees at the store -- in the storage area and restroom.
