(Adds comments from Senator Schumer on drone regulation)

NEW DELHI/ WASHINGTON, Jan 26 (Reuters) - A small drone crashed on the grounds of the White House in the early hours of Monday without endangering anyone and U.S. officials said they had identified the operator.
A person has come forward to take responsibility for flying the drone, a Secret Service spokeswoman said, without providing details about the individual. The agency said the drone was being flown for recreational purposes when it breached the secure perimeter of the presidential mansion.
A White House spokesman said the device, known as a "quad copter," did not appear to be dangerous.
The incident may enflame the debate among lawmakers in Washington over the need for drone regulations.
"There is no stronger sign that clear FAA guidelines for drones are needed," Democratic Senator Charles Schumer said, referring to the Federal Aviation Administration, which is responsible for regulating U.S. airspace.
The device, approximately two feet (61 cm) in diameter, was spotted flying at a low altitude at 3:08 a.m. EST (0808 GMT) before it crashed on the southeast side of White House grounds, Secret Service spokeswoman Nicole Mainor said in a statement.
Mainor said there was an "immediate alert and lockdown of the complex until the device was examined and cleared."
Mainor did not disclose the drone's manufacturer.

His wife, Michelle Obama, accompanied the president. Their daughters, Sasha and Malia, and their grandmother, Michelle Robinson, stayed behind.
"I don't have any reason to think at this point that the first family is in any danger," Earnest said.

The Secret Service also has come under scrutiny after several incidents involving White House security. Its director resigned in October, and an independent review concluded that it needs to build a better fence and hire more officers.
The U.S. Attorney for the District of Columbia will review the case and decide whether to prosecute, the Secret Service said.
