OAKLAND (KRON) –Oakland police used a helicopter to arrest two men accused of a string of armed robberies.

The duo was first spotted just before 9 a.m. when an Oakland school police officer tried to stop them in a vehicle near the area of Fruitvale Avenue and David Street, said Oakland police spokesperson Officer Johnna Watson.

Police said that the two men matched the description of the suspects in a string of more than six armed robberies Tuesday morning. Most of the robberies happened in the East Oakland and Fruitvale areas.

The armed men ran from their vehicle. Police set up a perimeter and started to search the area with the help of a police helicopter.

The helicopter was able to track the men from the air. With those sightings, as well as calls from people in the area, police were able to track the men to an empty house in the 2300 block of Mitchell Street.

After surrounding the house, the two men were arrested without incident.

Following their arrest, police searched the house for two guns thought to have been used in the robberies and have located some items stolen from victims.

Police have not yet released then suspects’ identities and are working to determine how many robberies they might be connected to.
