Sacramento police confiscated this evil clown mask after it was pulled off a robbery suspect at an Oak Park store on Saturday.

Surveillance video showed the encounter between 80-year-old Baldev Dhillon and the unidentified suspect unfold quickly inside Dhillon’s business on the 4000 block of 12th Avenue, clearly showing the suspect aim a gun at Dhillon as he stepped into the store.

Dhillon’s entire family, including two young grandchildren, was inside the store as the robbery took place.

“My legs were shivering,” said 11-year-old Hirdayjot Dhillon.

As the robber closed in on the store owner, Baldev hardly flinched before grabbing for the gun and throwing the suspect off balance. The suspect backpedaled quickly as Dhillon pressed his counter-attack and then fled altogether as the store owner grabbed the clown mask by its long dreadlocks, yanking the mask off his head.

Family members said they heard the click of the trigger as the robber tried to shoot, but the gun never fired.

Police believe the suspect is the same man who robbed two stores on January 19 while wearing the same mask. Shots were fired in both incidents, but no injuries were reported.

Bikram Dhillon, the son of the business owner, said he isn’t surprised his father jumped into action so quickly — he served as a police chief in India for 30 years.

“If somebody threatens his family, he will fight,” Bikram said.

A witness chased the unmasked suspect to a light blue sedan and described the man as a Hispanic adult.
