Third Precinct officers said Patel was involved in an accident at Jericho Turnpike and New Hyde Park Road in New Hyde Park at about 9 p.m.

There were no injuries, police said.

The child was released to a family member.

Under Leandra’s Law, passed in 2009, drivers who are intoxicated or impaired by drugs with a child 15 years or younger in the vehicle can be charged with a felony. The law was passed after the death of Leandra Rosado, 11, who was killed Oct. 11, 2009, in a DWI accident after the minivan in which she was a passenger crashed on the West Side Highway in Manhattan.
