A police chief likened the conflicting accounts of an accidental overdose at Isiah Thomas' home to a "cover-up".

Thomas said on Saturday that it was his teenage daughter that need medical treatment early Friday.

"It wasn't his daughter," Harrison Police Chief David Hall said. "And why they're throwing her under the bus is beyond my ability to understand."

Authorities were called to Thomas' Westchester County home, where police said a 47-year-old man was taken and treated for an overdose of sleeping pills.

Several media outlets reported that police confirmed it was Thomas, 47, who went to the hospital.

Reached on his cell phone Friday, Thomas told the New York Post he had not been treated for a sleeping pill overdose, and that it was his daughter.

It "wasn't an overdose," he told the newspaper. "My daughter is very down right now. None of us are OK."
