A US mum has pleaded not guilty to two charges of child endangerment after a prank with duct tape

A MOTHER who posted a text message with a picture of her son with his head covered in duct-tape says she has done nothing wrong.

Tiffany Ennis, 31, of Sandusky, Ohio, has pleaded not guilty to two charges of child endangerment.

Ennis allegedly wrapped duct-tape around the forehead, eyes and mouth of her son, eight - which she posted to the boy's father Rudy Yado who contacted police - and to the head of an 11-year-old girl, ABC News reported.

Ennis told police she was playing around with duct tape with her friend and their children and that she had wrapped tape over her son's eyes and mouth because they both thought it was funny, the police report said, FOX 8 reported.

Ennis said she did the same to the 11-year-old girl.

According to the report, Ennis told police the children were not hurt and no marks were found on them. Ennis said it was not meant to be hurtful and they were joking around.

Detective Sergeant Dana Newell of the Sandusky police department told ABCNews that he went to Ennis' home on February 19 with Erie County Child Services to check on the children.

Upon investigating the complaint, Newell said Ennis was subsequently arrested for duct-taping the children's heads and eyes, and transported to the Sandusky police department. She is scheduled to reappear before on May 30.

Det Sgt Newell said he could not confirm as to whether Ennis' son was still with his mother.
