A man robbed a woman of her wallet Thursday, but the woman fought back with pepper spray, officials said. The robbery took place about 2 p.m. on Diamond Bar Boulevard, just south of Grand Avenue, Los Angeles County sheriff’s Lt. Frank Rivera said.

The robber pushed the woman and grabbed her wallet when it fell to the ground, the lieutenant said. The woman sprayed pepper spray toward the robber, though it was unclear if it hit him in the face.

Deputies searched the area for the robber, but he was not found, Rivera said. A detailed suspect description was not available.

The woman, who was in her 20s, was examined by paramedics but did not appear to have suffered significant injury, Rivera said.
