An armed man has died "apparently by his own hand" following an hours-long standoff with police after he barricaded himself in a Connect Wireless store inside a Crescenta Valley shopping center, KTLA is reporting.

From KTLA:

No shots were fired by sheriff’s deputies, who entered the store more than five hours after the incident began, the Sheriff’s Department said in a statement. No deputies or citizens were injured.

Los Angeles County Sheriff's deputies responded to the area at around 4 p.m., clearing the area of shoppers and surrounding the man, who is alone inside the store.

The man first went into a Rite Aid, showed a gun, and demanded a prescription. After he received the pills, he ran away from the store, according to NBC Los Angeles.

The man then barricaded himself inside Connect Wireless, a Verizon Wireless third-party vendor.

A spokesperson for the sheriff's office told NBC Los Angeles they believe the man ordered everyone out of the store and no hostages had been taken. The man had threatened to commit suicide, according to KTLA.

A heavily-armed SWAT team was on the scene along with a negotiator to try and get him to surrender, according to NBC Los Angeles.
