According to a release from county police, a 27-year-old man and 19-year-old man were confronted by a group as they walked to the station on 751 West Patapsco Avenue, which straddles the border between Baltimore and Baltimore County.
The group fled before police arrived and were seen on foot headed east toward the Cherry Hill area of Baltimore.
Det. Cathy Batton, a spokeswoman for Baltimore County police, said the assault occurred in the county.
The two men were each stabbed multiple times in the upper body and had their cell phones and other items taken.
Both sustained "serious injuries," according to the release, and were taken to the University of Maryland Shock Trauma Center.
No update on their condition was available as of 1 p.m. Tuesday, July 19, Batton said.
A 45-year-old man who tried to tried to stop the robbery was punched but did not need medical assistance, the release stated.
Batton said it is uncertain whether the person who punched the 45-year-old also stabbed the other two.
The police believe a black male, in his late teens, responsible for the stabbings, the release stated.
The police have requested that anyone with information about the suspect should contact Metro Crime Stoppers at 1-866-756-2587.
