WORCESTER, MASS. >> The purported leader of a gang that held up several Worcester sub shops at gunpoint has been held on $35,000 bail.

Prosecutors say 27-year-old Brian Lacroix, of Holden, wielded the gun and was the "primary perpetrator" of the five robberies at four different sandwich shops in March and April.

The Telegram & Gazette reports that Lacroix's lawyer entered not guilty pleas on his client's behalf to five counts of armed robbery while masked. Prosecutors sought $100,000 bail.

Lacroix and three alleged accomplices were arrested April 16 in a vehicle that matched the description of one used in a holdup at a Subway shop.

His defense attorney said Lacroix has a drug problem and asked that he be released on personal recognizance so he can enter a drug treatment program.
