An undercover investigation of the Uber car-hailing service caught its drivers sexually harassing female passengers and blatantly violating various city regulations, according to a report released Tuesday by celebrity private eye Bo Dietl.

One alleged harassment incident involved a lecherous Uber driver telling a rider “that the people in Bangladesh would love her because she is attractive,” according to the report, which was commissioned by the Taxicab Service Association, an industry group ­opposed to Uber.

Other alleged wrongdoing included drivers cutting illegal side deals with passengers for future trips and making a curbside “hail” pickup — which can be made legally only by yellow cabs — near Union Square.

One driver even claimed a fellow hack once took a drunk woman on a $250, three-hour trip that should not have taken more than 10 minutes — and ended only because the woman woke up, the report says.

The TLC said Uber on Friday coughed up its electronic trip records — which the TLC plans to check for any violations of city law.

A spokesman for Uber said the company hoped the TLC would “earnestly and closely safeguard” the information, and said the claims in Dietl’s report “have no merit.”
