The Boston Police Department reports three teens didn't get far with the 10 to 15 laptops they allegedly stole from a Dorchester Avenue computer-repair shop Monday morning.

Police say the three entered Comp-Net Solutions, 1120 Dorchester Ave., around 11:20 a.m. and asked an employee if he sold chargers. When he said no, one took out a black handgun and pointed it at him, while the other two gathered up the laptops from display cases. Before leaving, they took his wallet as well.

Police say officers who swarmed the area found assistance from witnesses who pointed them to 12 Roach St. a couple blocks away: "After officers set up a perimeter around the dwelling, officers were able to engage the suspects until they emerged from the residence."

Jason Toomer, 19, and Dennis Wilson, 18, both of Dorchester were charged with armed robbery, as was a 16-year-old, too young to have his name released. Toomer had an additional charge of assault and battery added today after he allegedly attacked a court officer while awaiting arraignment in Dorchester District Court, the Suffolk County District Attorney's office reports.

A bail set $100,000 bail for both Toomer and Wilson and revoked Toomer's earlier bail on an unrelated assault case, the DA's office says. The juvenile was released on personal recognizance.
