BOSTON?A man was arraigned Monday on charges that he sexually assaulted a woman during an airline flight to Boston from Dallas.

Deepak Jahagirdar, 51, of Scottsdale, Ariz., pleaded innocent to charges of rape, assault with intent to rape and interfering with aircraft operations, said David Procopio, spokesman for the Suffolk District Attorney’s office.

Jahagirdar, a marketing manager, was sitting next to the alleged victim on Delta Flight 2100 early Sunday, according to prosecutors.

Procopio said Jahagirdar assaulted the woman while she was asleep.

State troopers boarded the plane on Sunday at Logan International Airport and arrested Jahagirdar, officials said.

Bail was set at $2,500 and a hearing was set for April 29.

Jahagirdar is married with two children, Procopio said. His attorney, James W. Lawson, declined comment.
