PLYMOUTH MEETING, Pa. (CBS) - Three men were arrested in connection with a robbery at a Burger King in Montgomery County Thursday morning.

The three suspects – Edward David Cottle, Charles Robinson, and James McDuffie, all from Philadelphia – were arrested in Conshohocken after they were stopped for speeding, according to authorities.

At about 5 a.m., officers in Plymouth Township were called out to a Burger King restaurant in the 400 block of West Ridge Pike after receiving reports of an armed robbery. The victims reportedly told police the robbery was committed by two black males, and at least one of them had a handgun. After the robbery, the suspects reportedly placed the victims in the freezer and then fled the restaurant.

While Plymouth police officers were investigating at the scene, a Conshohocken Borough police officer observed a vehicle speeding southbound on Fayette Street.

After stopping the vehicle, the Conshohocken officer alerted Plymouth police who, when they arrived at the location, discovered a firearm in the car. The men were subsequently removed from the vehicle.

The robbery victims were taken to the scene of the traffic stop where they positively identified the men involved in the robbery.

A search warrant was executed and detectives were able to find evidence in the car that linked the suspects to the robbery, according to authorities.

All three suspects have been arrested and are charged with a slew of offenses including Robbery, Terroristic Threats, Possession of Instruments of Crime and Assault.

The three suspects are awaiting arraignment.
