Police in California are searching for a woman who was caught on surveillance video ripping down a "thin blue line" flag meant to support law enforcement.

The unidentified woman was spotted on the 2400 block of Santa Clara Avenue on March 26, according to a Facebook post from the Alameda Police Department.

Video footage showed the woman donning a yellow sweater or sweatshirt as she walked down a sidewalk with someone. The two passed a "thin blue line" flag posted outside a storefront when the woman jumped up to grab it and tried to pull it to the ground.

Before the flag hit the ground it appeared to hit her in the head. The woman then dragged the flag and tossed it on the ground nearby.

Investigators said that the woman "later returned to further vandalize the victim's property."
