Police have arrested one of three suspects in a Maplewood home invasion robbery in which a 75-year-old woman was choked unconscious.

North St. Paul and Maplewood police arrested the 25-year-old man about 2 a.m. Tuesday during a traffic stop. He was arrested without incident, police said.

Authorities are investigating possible connections between the North St. Paul man, who had not been charged as of Tuesday afternoon, and the Jan. 2 robbery in the 1700 block of Gervais Avenue. according to a Maplewood police news release. The man is jailed on suspicion of Financial Transaction Card Fraud, a felony. He has not been formally charged. Maplewood police on Monday released surveillance footage of the suspects using credit cards believed to be connected to the robbery.

“The level of depravity and violence exhibited by the suspects is beyond comprehension,” Maplewood Police Chief Paul Schnell said in a written statement. “The victim in this case demonstrated no resistance to the suspects, which makes the intent and motive for strangling the victim inconceivable.”

Police are still looking for the other two suspects — a man and a woman.

The 75-year-old woman told police that a woman rang her doorbell, asked to use the phone and then brandished a handgun and forced her way inside when her request was denied.

The female intruder placed a call on her cellphone, and two male suspects soon arrived inside the home. One of the men bound the elderly woman’s hands while his two accomplices ransacked the home, taking jewelry, credit cards, keys and the woman’s driver’s license.

One of the men then ordered the victim onto the floor and choked her with an article of clothing until she was unconscious. The woman regained consciousness and sought help at a neighbor’s home.

Police are also investigating whether the three suspects are linked to the Dec. 27 burglary of a nearby home that was unoccupied at the time.
