An alleged New York City conman, who told police he took a cab from the Big Apple to Best Buy in Watertown to upgrade his phone, was arrested after police discovered he wasn’t who he claimed.

Police arrested 22-year-old Darrel I. Grosvenor of 440 164 St. Apt. 6 in New York on Feb. 3 for alleged identity fraud, and two counts of attempting to commit a crime, and to wit larceny over $250.

Officers were dispatched to Best Buy at the Watertown mall at 5:30 p.m. on the report of a possible fraudulent incident, Watertown Police Lt. James O’Connor said. Upon arrival, officers spoke with a store manager who stated that Grosvenor had entered the store and was trying to upgrade a cell phone service. According to the employee, he purchased two iPhone 6s phones valued at $399.99 each.

The manager said he requested Grosvenor’s drivers license, which is standard practice when upgrading phone plans, the cellphone number, the zip code of his hometown, and the last four digits of his social security number, O’Connor said. The driver’s license matched the name on the account, but Grosvenor didn’t know the zip code or the social security number.

The manager became suspicious when Grosvenor couldn’t answer his questions tried calling the phone Grosvenor was trying to upgrade and got a voice mail with a different voice on it, O’Connor said. The manager then called police.

Officers discovered the Grosvenor had stolen an identity of a person from Connecticut, O’Connor said. The license he had produced was also a fake.

“It was a fake license with correct info of the real guy who owned the service,” O’Connor said.

That wasn’t all officers found.

“As officers investigated, they found another Connecticut license with Grosvenor’s picture on it, and another, different named on it,” O’Connor said.

When police asked Grosvenor to explain why he had two licenses, he told them he was from New York, O’Connor said.

“He said he took a cab from New York City to Best Buy in Watertown specifically to upgrade his phone,” O’Connor said. “And his idea was to go back to New York City via cab from Watertown.”

Officers also contacted the person whose identification was stolen, and confirmed that the ID had been stolen, O’Connor said.

Grosvenor was placed under arrest, O’Conner said. Officers later discovered that Grosvenor had an outstanding warrant out of Kinsgbury, New York for identity fraud, O’Connor said. Police also alerted Connecticut State Police of the situation as well.
