A registered sex offender has admitted that he improperly touched a sleeping woman aboard a flight from Israel to New Jersey.

Federal prosecutors say Yoel Oberlander pleaded guilty Wednesday to assault with intent to commit stalking. The 36-year-old New York state man faces up to 10 years in prison when he's sentenced June 28.

Prosecutors say the incident occurred aboard an El Al flight from Tel Aviv to Newark Liberty airport in May 2016.

The victim was sitting next to Oberlander, who admitted touching her in the chest, upper thigh and hand without her consent. He also admitted doing so with the intent to harass and intimidate her.

Authorities have said Oberlander was convicted in 2002 in New York of sexual abuse involving an 11-year-old girl.
