NEW YORK (AP) - The family of a Korean immigrant who died after allegedly being pushed into the path of a New York City subway train has filed a lawsuit against the city's transit authority.

The lawsuit filed on Friday by the family of Mr Han Ki Suck seeks unspecified damages stemming from his Dec 3 death. It accuses the Metropolitan Transportation Authority of negligence.

Police said a homeless man admitted pushing Mr Han onto the tracks but said the latter was drunk and instigated the confrontation.

Naeem Davis has been charged and is being held without bail. His attorney has said Mr Han went after his client.
