NEWPORT NEWS, Va. (WVEC) -- Police arrested a substitute school bus driver who is accused of propositioning a 15-year-old girl and giving her alcohol.

Officers said that 54-year-old Timothy Mears Dixon began communicating with the teenager using the app "Whisper."

The criminal complaint filed in the case states that Dixon provided the girl with a telephone number and that the two of them continued communicating using phones. One of the messages Dixon is accused of sending suggested the two have anal sex and said that he would "bring pizza." Another asked: "what if I held you down and raped you."

Dixon and the 15-year-old girl met in person. Police said he bought alcohol for her and took her to his home on Susan Constant Drive where the girl drank the alcohol.

A detective questioned Dixon after the girl told police about the relationship between the two. The criminal complaint says that Dixon admitted that he and the 15-year-old communicated, that he sent the texts, and that he bought alcohol for her to drink at his home.

Dixon faces charges of Use of Communication Systems to Facilitate Certain Offenses Involving Children and Contributing to the Delinquency of a Minor.

Spokeswoman for Newport News Public Schools Michelle Price told 13News Now that Dixon was a substitute bus driver with the division since December 2013. She added that in cases such as this employees are suspended without pay.
