A 35-year-old man is accused of using his computer-repair business to rip off clients.

Billie Conley, who now lives in Woodbridge, had based his business, Ridgefield Tech, LLC, in Stratford, police said. He was charged on a warrant Thursday with 17 counts of first-degree identity theft, two counts of third-degree larceny and one count each of second-degree forgery and second-degree computer crimes. He turned himself at police headquarters.

Police began investigating Conley when a Sedan Terrace resident reported $75,000 worth of unauthorized online payments made from his mother's bank account last year.

The man said he noticed over the summer that he was no longer receiving the mother's bank statements via email, but assumed it was a glitch on the bank's part. Then, last November, he noticed a series of bill payments to AT&T, United Illuminating, Southern Connecticut Gas, Frontier, Wide Open West cable and Verve that were not authorized from the account. His mother did not have accounts with AT&T, Frontier, Wide Open West or Verve, according to the report.

The man also told police that in July he had problems with a computer purchased at Staples office supplies. Staples referred him to Ridgefield Tech for service. He said Conley came to his house and repaired the computer. Pleased with that work, the man told police he had Conley do additional computer work for him. That apparently gave Conley the opportunity to give himself remote access to the computer, according to the report -- the man said he often noticed the computer's cursor moving when no one was at the device.

While investigating the complaint, police learned about another Fairfield resident who had hired Ridgefield Tech. That resident told police a check was taken from his check book, and later forged and cashed for $3,400.

Police said Conley initially denied wrongdoing.

But later, according to the report, he told police he didn't know why he did such things. The report indicated Conley had been arrested in 2010 in Stamford, Darien and Greenwich for stealing financial information from computer customers.

Bond was set at $25,000 and Conley is scheduled to appear April 10 at state Superior Court in Bridgeport.
