A 23-year-old Somerville man told Cambridge Police Officer David Lee he was riding his skateboard on the sidewalk at Broadway near Sennot Park in Cambridge at about 3 a.m. when a dark colored SUV drove toward him head-on. The Somerville man jumped off his skateboard and began running away from the three suspects toward Prospect Street. The victim told police one of the suspects possibly had a handgun, according to reports.

Police said three Plymouth men went on a robbery spree last week, allegedly driving around Cambridge in their SUV and attacking unsuspecting pedestrians on the streets.


Devin McClellan and Michael Gallivan, both 19, and 20-year-old Clayton Walsh, were arrested and charged for armed robbery and assault and battery with a dangerous weapon. Walsh was also charged with driving to endanger, being a person under 21 transporting alcohol and motor vehicle charges.


Cambridge and Harvard University police, following a witness’ tip, pulled over a 2002 blue Ford Explorer on Meacham Road in Porter Square and arrested the men shortly after the third robbery.


Cambridge cops suspect the trio robbed three separate people within a 20-minute period starting just after 3 a.m. June 5.


A 23-year-old Somerville man told Cambridge Police Officer David Lee he was riding his skateboard on the sidewalk at Broadway near Sennot Park in Cambridge at about 3 a.m. when a dark colored SUV drove toward him head-on and the people inside began screaming out of the window at him, according to police.


The doors to the SUV then flew open and three suspects inside hopped out and allegedly began running toward the skateboarder. The Somerville man jumped off his skateboard and began running away from the three suspects toward Prospect Street. The victim told police one of the suspects possibly had a handgun, according to reports.


The suspects allegedly chased the victim for about 1,500 feet before they gave up, returned to their SUV and drove away toward Norfolk Street, stealing the victim’s gray skateboard with green stripes. The victim ran into Store 24 on Broadway and asked to use the phone. Police said it took the victim 10 minutes to convince the store clerk to let him call 911.


As police were interviewing the victim, 911 dispatchers received two more reports of the same suspects allegedly robbing victims at the intersection of Harvard and Windsor streets and at Sidney and Green streets.


Minutes after the skateboarder’s run-in with the alleged thieves, a 23-year-old Cambridge man was walking on Harvard Street across from Windsor Street while listening to his iPod when suddenly he felt a forearm come across his neck. He said one of the robbery suspects allegedly demanded his bag containing his wallet, pink Sprint cell phone, iPod Nano and a set of keys. One suspect then told the victim to run before the three suspects allegedly ran away on Harvard Street.


A witness to the third robbery on Sidney Street in Cambridge — where the suspects allegedly hit their robbery victim with a metal chain — tipped off police that the suspects drove away in a blue 2002 Ford Explorer. Police stopped their car in Porter Square and arrested the men after the skateboarder and Cambridge victim identified them as the suspects. The stolen skateboard and the Cambridge man’s cell phone, iPod, keys, driver’s license and debit card were found inside the SUV, police reports state.
