The shooting occurred Thursday at 11:30 p.m. near the intersection of Clark Avenue and Pacific Coast Highway.
Undercover police were conducting a surveillance operation and investigating a vehicle believed to be involved in a series of armed robberies that occurred earlier in the week, according to Shaunna Dandoy with Long Beach police.
A suspect was confronted by officers after he exited the vehicle and entered the 7-Eleven. An officer-involved shooting then occurred, Dandoy said.
The suspect died at the scene. Another suspect was taken into custody.
Police said they recovered a gun the suspect was allegedly carrying.
No officers were injured and no additional injuries were reported.
Pacific Coast Highway between Anaheim Street and Granada Avenue, and Clark Avenue between Anaheim Street and Atherton Street were closed for several hours but were eventually opened back up.
An investigation was underway.
