West Hartford police arrested a 57-year-old emotionally disturbed woman who they said stabbed another woman in the head outside a CVS store on Friday morning.

The attack outside the CVS at 1099 New Britain Avenue early Friday morning was random, according to police.

The 27-year-old victim had just made a purchase a and was leaving the store when Gloria Drummer, 57, of West Hartford, attacked her for no reason, and stabbed her in the head several times with a large knife, according to police.

Drummer appeared to have waited for the victim to leave the store before the attack, police said.

When the victim fell to the ground, her boyfriend and CVS employees, rushed to help her and Drummer walked across the street and sat at a bus stop, where police took her into custody, police said.

Witnesses said Drummer had been inside the store, mumbling to herself, before the stabbing and appeared to be emotionally disturbed.

The victim’s injuries are not life threatening and she has been released from the hospital.

Drummer was charged with first-degree assault and breach of peace, then taken to UConn Medical Center to be evaluated.

She has been released and was arraigned on Friday morning. It's not clear if she has an attorney.
