SAN FRANCISCO (KRON) — Lesbian Gay Bisexual Transgender Pride Celebration event organizers announced that for the first time in the festival’s 46-year history, attendees will be searched for weapons. This is San Francisco’s response to massacre inside an LGBT nightclub in Orlando on June 12.

According to organizers, each person will walk through metal detectors and guards will do a second screening using a wand to search for contraband.

Officials are anticipating long lines as each person will have to pass through the gates to enter the festivities at San Francisco’s Civic Center.

City leaders acknowledged the inconvenience but said these measures were important to help ensure public safety.

In addition to enhanced security at the gates, additional San Francisco Police Department officers have been assigned to patrol the event.

Organizers are advising attendees to avoid bringing bags as they could slow down the screening process.

San Francisco’s Office of Emergency Management has created a text alert system so that party-goers can receive information and news updates about the event.

The two-day event will feature live entertainment, food, and a parade on Sunday. The free event is scheduled from noon to 6 p.m. at Civic Center.

The Parade kicks off at 10:30 a.m. at Market and Beale, and ends at Market and 8th Street in downtown San Francisco.
