Naugatuck police arrested the second suspect Wednesday wanted in connection with a daytime robbery on Orchard Terrace last November.

And now, police said the incident that sparked the alleged armed robbery on Nov. 28 started over a planned drug deal that went awry.

Isaiah Freeman, 20, of 140 Mill St. in East Haven, was taken into custody after police picked him up in Naugatuck around 4 a.m. on Wednesday.

Freeman was wanted on a warrant charging him with a conspiracy to commit first-degree robbery, a conspiracy to commit sixth-degree larceny, making a false statement in the second-degree, a breach of peace and accessory to criminal liability for acts of another.

Police accuse Freeman of assisting the main suspect in the incident, a 16-year-old Naugatuck juvenile, who was arrested last month on a series of charges including weapons possession and robbery. Freeman was at the scene when the 16-year-old pointed a gun at three people, two women and one male, who were seated in a car on Orchard Terrace, said Lt. Robert Harrison, Naugatuck police spokesman.

The juvenile, however, disputes police's charge that he had a gun. Harrison said the 16-year-old claimed it was a metal pipe that was lodged up his sleeve, which could have had the apperance of a gun, police said. Harrison noted that no weapon was ever recovered in the incident.

“At the initial time there was no claim that [the suspects and the victims] knew each other,” Harrison said.

But, as the investigation continued, police said further information developed.

Harrison said one of the females had previously met the 16-year-old at a Naugatuck market and had agreed to sell an ounce of marijuana to the juvenile for $110. The two coordainted the sale via a phone call and the female victim and the juvenile agreed to rendezvous on Orchard Terrace.

But meanwhile, the juvenile had told Freeman he planned on robbing the woman, police said. He enlisted Freeman to come along, as he believed it would be more intimidating to have a second person there during the robbery, police said.

After pointing the alleged weapon at the victims, they handed over the marijuana and a $150 wallet. Then, Freeman and the 16-year-old fled the scene before police arrived.

Harrison said no further arrests are expected in the case. He declined to state why the victims were not arrested.

Freeman was held on $15,000 court-set surety bond and was due to be arraigned in Waterbury Superior Court on Wednesday.
