A toddler was hospitalized and a woman arrested this week, after she allegedly fed meth to the child as he played in a popular Berkeley Park.

The strange and disturbing saga began Monday at around 3:31 p.m., when a woman later identified as 36-year-old Sayyadina Thomas allegedly approached a 2-year-old at Berkeley's People's Park as he played with his nanny, KRON 4 reports.

As the child climbed on a play structure, Thomas allegedly grabbed him and shoved something into his mouth. The Daily Californian reports that the nanny immediately checked his mouth, but found nothing. She called the University of California Police Department, which responded to the scene.

As police detained Thomas for a psychiatric evaluation, paramedics transported the child to UCSF Benioff Children's Hospital Oakland, NBC Bay Area reports. While speaking with police,Thomas said that she gave the child meth. An evaluation at the hospital confirmed that the child had indeed consumed methamphetamine. He was promptly treated, and is expected to make a full recovery.

"He was playing with the nanny in the play yard," a witness to the incident told NBC. "She just walked up to him a grabbed him, and she stuck her hands in his mouth."

ABC 7 reports that Thomas is well-known to park denizens, with one saying that "She's not a very good person. She steals everyone's stuff. She runs around talking to herself. She's crazy."

"Police also know Thomas, who they say lives in the park, alone," ABC 7 reports. "She's been busted for trespassing, indecent exposure, and probation violations."

And this time she faces charges of attempted murder, police say. According to ABC 7, she is expected to be arraigned Wednesday, and remains in police custody.
