Two people were killed during a shooting at the University of California, Los Angeles (UCLA) on Wednesday morning in an apparent murder-suicide. The school was immediately placed on lockdown.

The Los Angeles Police revealed that the gunman was among the two people who were declared dead after the lockdown, according to the New York Times.

Police believe that a murder-suicide took place. “It appears it is entirely contained. We believe there are no suspects outstanding and no continuing threat to UCLA’s campus,” Los Angeles Police Chief Charlie Beck said.

A gun was discovered at the scene, and Chief Beck said that a suicide note might have been left by the gunman. It is unknown whether the victims were students, employees or visitors.

Hundreds of people were in the Engineering IV building at the time of the shooting, which took place at around 10 a.m., police said. Students and employees received text messages and email alerts informing them to find and take shelter.

After the lockdown was lifted, the UCLA offered counselling services to its students, faculty and staff affected by the incident, according to the university’s website.

Classes and evening events were cancelled throughout the rest of the day. Final examinations and commencement will still take place as scheduled.

“We want to resume normal operations as quickly as possible, so we will resume scheduled classes tomorrow morning,” UCLA Executive Vice Chancellor and Provost Scott Waugh said.

“Faculty, staff and students should show up tomorrow and go through their regular routines and complete the quarter as planned.”

Waugh also revealed that school officials will continue to inspect all campus measures related to active shooting in light of the tragedy.

“We’ll learn from this event and we’ll learn how we need to work as cooperatively as possible with the different law enforcement agencies to make sure that we can handle these kinds of situations effectively and safely for the students, faculty and staff,” he said.
