Officers from multiple law enforcement agencies descended on San Francisco's Jefferson Square Park Wednesday evening, where rampant drug use earned it the name "Zombie Park," arresting dozens of people.

A multi-agency law enforcement operation was carried out in the overnight hours into Thursday morning at a San Francisco park. San Francisco police say the bust at Jefferson Square Park is part of an ongoing strategy to crack down on open-air drug markets.

San Francisco Police Department's operation led to nearly 90 arrests in Jefferson Square Park for drug-related activities.
