Report: Serena locks self in panic room

Serena Williams fled to the panic room in her Los Angeles mansion when she mistook a sports association drug tester for a dangerous intruder.

The tennis legend’s assistant called 911 around 6 a.m. local time last Wednesday and told the emergency operator that a prowler had been spotted at the luxurious property, TMZ reported.

Williams retreated to her panic room in a bid to protect herself.

But the intruder turned out to be a random drug tester who stopped by unannounced for a urine sample in accordance with tennis’ anti-doping policy.

Cops responded to the 911 call but quickly left the property when the misunderstanding was discovered. It was not known whether Williams submitted to the drug test.
