Cambridge and Lawrence Police report the arrest of two adults and two teens for an armed-robbery spree early yesterday that started in Brookline and Boston, moved to Cambridge and then ended in Lawrence, where police managed to catch them.

Police say that after the Brookline, Boston and Cambridge robberies - in which at least two victims were beaten - Michael Ellis, 20, of Haverhill, King Sheman, 19, of Newburyport; and two male juveniles from Newburyport and Amesbury drove to Lawrence, where they pistol whipped a robbed a man of his phone and wallet. Police say that proved their undoing - Lawrence Police stopped and arrested them soon after.

Police say they recovered the black Volkswagen they'd used to get from robbery to robbery and two black and silver BB guns used in the attacks.

Although the four were formally charged with just the Lawrence attack, Cambridge Police add:

Due to the preliminary investigation and property recovered, the departments are highly confident that these suspects were involved in the armed robberies that took place throughout the four cities Friday morning. Cambridge, Boston and Brookline anticipate formally charging the suspects following the completion of their investigation.

Innocent, etc.
