PORTLAND, Maine — Portland police arrested a 34-year-old woman they say returned to a local drugstore just less than two hours after allegedly holding the place up with threats of an explosive.

Police arrested Elisabeth Sanborn of Portland on Class A robbery charges when she returned to the 340 Allen Ave. Walgreens just before 11 a.m. Sunday.

Sanborn was the primary suspect in a 9 a.m. crime that same morning, when a pharmacy workers claimed a female demanded prescription medication and, according to Lt. James Sweatt of the Portland Police Department, “indicated a threat and referenced an explosive device.”

Investigators brought a bomb-sniffing dog to the site and conducted a protective sweep of the suspect’s vehicle in the parking lot and found no explosives, Sweatt said in a Sunday afternoon announcement.

Police say the investigation is ongoing and are asking anyone with information about the robbery to call 874-8575, or provide anonymous tips by calling 874-8584, texting the keyword “GOTCHA” and a message to 274637, or visiting the website www.portland-police.com.
