Two Boston men cross the river for a gun battle in Cambridge; one crashes car in Somerville, police say

Cambridge Police report the arrest of two men who exchanged some 20 rounds without hitting each other - or anybody else - in an apparent gun battle on Hurley Street in East Cambridge.

Police say they arrested one of the men at the scene before he could even ditch his gun, and add:

Another Boston resident in his early 20s was taken into custody by the Somerville Police following a car crash on the McGrath Highway and a foot chase.
