There is now a reward offered for information helping to locate an Edgemont teen who has been missing for more than a week.

Christine Kang, 16, left her parent's house on Robin Hill Road in Greenburgh after an argument on Jan. 2 and hasn't been seen or heard from since, prompting a massive search by police and volunteers.

The last known sign of Kang was on surveillance video at Grand Central Station in Manhattan.

Friends, family and fellow students have expanded their search to Manhattan and say they are not giving up until they find her. Volunteers have posted fliers inside the terminal and outside on lamp posts throughout midtown Manhattan.

Kang is considered an endangered juvenile because she was last seen wearing only pajamas, boots and no coat.

Greenburgh police are working with the NYPD, MTA police and several other law enforcement agencies as part of the massive effort to find Kang.

Anyone with information on Kang's whereabouts is asked to call the Greenburgh Police Department at (914) 989-1700.
