A man who police believe was involved in the November smash and grab at a New Canaan jewelry store is wanted on federal charges by the FBI.

New Canaan police said Ralik Hansen, 28, whose aliases include Ralik Taylor, Rahlik, Rah and Ratchet, should be considered armed and dangerous. He has been federally indicted and is at large, according to a release from the New Canaan Police Department.

On Nov. 6 at around 4 p.m., four males attempted to enter Henry C. Reid & Son Jewelers, 72 Elm St., but were stopped when an employee locked the front door. One of the suspects shattered a front display window with a tool resembling a sledge hammer, according to police. The suspect reached in through the broken glass and took three Rolex watches with an approximate value of $55,000, police said.

The four suspects fled on foot behind a row of business, where it is believed that they drove off in a Chevrolet Malibu with tinted windows and New York plates. Blood and skin tissue evidence was recovered at the scene, police said.

In addition to Hansen, the investigation identified Roberto Grant, 33; Ronald McIntyre, 36; Sean Robinson, 42; and Allen Williams, 35, as having committed the crime.

Grant, McIntyre, Robinson and Williams were indicted, arrested and are in federal custody, according to a release from New Canaan police.

According to a release from the U.S. Attorney's Office, the five men were part of a multi-state robbery crew that "used violence, including firearms, to steal more than $1 million in luxury watches."

Federal officials unsealed a seven-count superseding indictment Monday charging eight members of a crew operating across New York, New Jersey, Virginia and Connecticut with robbery conspiracy and robberies of high-end jewelry and watch stores.

In addition to Robinson, Williams, Hansen, McIntyre and Grant, Terrell Ratcliff, 22; Tyrone Dehoyos, 35; Sean Robinson, 42; and Kendal Thompson, 30, were indicted on charges of robbery conspiracy, substantive robbery and firearms offenses. Five of the defendants -- Williams, Grant, Ratliff, Dehoyos and Thompson -- previously were arrested and detained pending trial, according to the release. On Monday, Robinson was arrested in Brooklyn, N.Y., and McIntyre was transferred into federal custody, and both were arraigned before Judge Robert P. Patterson and detained pending trial.

According to the allegations contained in the superseding indictment, other court documents previously filed in federal court and statements made in court Monday report that between approximately July 1, 2013, and Jan. 30, 2014, a highly organized crew engaged in a series of violent robberies of high-end jewelry and watch stores located in four states and smashed display cases with hammers while customers and employees were in the stores. The crew used violence as necessary to carry out the scheme.

For example, during one robbery in September 2013 in Brooklyn, two of the robbers displayed handguns, and a store owner was shot when he attempted to prevent members of the crew from fleeing with stolen watches.

In another robbery in August 2013 in Richmond, Va., the robbers used a handheld stun gun to subdue a female store employee before fleeing with more than a $100,000 in watches.

Among the stores robbed by the crew are Cartier in Manhattan, N.Y.; the Borgata Hotel and Casino in Atlantic City, N.J.; Schwarzschild's Jewelers in Richmond; Martin Jewelers in Cranford, N.J.; Henry C. Reid and Sons Jewelers; and Litan Jewelers in Brooklyn.
