Workers at a Yelp office in San Francisco are concerned after another employee was detained by police on Friday afternoon.

A Yelp worker says the employee in question sent an e-mail saying he was going to shoot people at the office and then kill himself.

People KRON4 spoke with say the incident was handled quickly, but with recent workplace shootings, like the latest in Maryland and Wisconsin, employees on high alert.

A KRON4 viewer sent an exclusive video of a man taken into custody by San Francisco police. This is inside 55 Hawthorne Street in San Francisco in one of the Yelp offices.

According to police, the call came in around 2 p.m. with a report of a person wanting to hurt himself.

Officials detained the male employee, and he was taken to the hospital for a medical evaluation. There were no arrests or injuries

But an employee KRON4 spoke to, who wants to remain anonymous, is telling KRON4 they heard this man was armed and a threat was made to shoot co-workers on Friday.

“Apparently, he had sent some e-mails saying that I’m coming to work, I have a gun or I’m armed, and I’m going to shoot my co-workers and I’m going to shoot myself,” the source said.

Yelp sent a message to all employees addressing the incident:

“We received word earlier this afternoon that an employee at 55 Hawthorne might have brought a weapon to the office. For the safety of all employees, we notified law enforcement.”

San Francisco police responded and resolved the situation peacefully and without incident.

While no weapon was found and no one was hurt, the employee was detained for his own wellbeing.

A Yelp spokesperson sent KRON4 the following statement in response:

“There were concerns about the welfare of an employee that led to police notification. SFPD resolved the situation onsite peacefully and without incident. The individual did not have a weapon.”
