(CNN) An 87-year-old grandmother using a knife to cut dandelions in the woods near her rural Georgia home last week was taken down by a police Taser and arrested, according a police report.

Martha Al-Bishara was arrested for criminal trespass and obstruction of a police officer, according to the report. Chatsworth Police said Al-Bishara did not drop a steak knife despite several commands and a demonstration by officers. At one point, she walked toward officers with the knife, police said.

Police had gone to a wooded area near a Boys and Girls Club last Friday after an employee called 911 to report that an elderly woman was walking around with a knife in the community, around 80 miles north of Atlanta.

"There's a lady walking on the bike trails, she has a knife and she won't leave," the caller told a dispatcher. "She told me she doesn't speak English, and she's walking up the trail with a knife towards me."

"It looks like she's walking around looking for something, vegetation to cut down or something. She has a bag too," the caller said.
