The Raging Bull star and his wife Grace Hightower headed to the West 58th Street firehouse to express their gratitude to brave workers who tackled the flames that broke out in their multi-million dollar home in Central Park West in June (12).
The couple spent hours chatting to the New York City Fire Department crew and even treated them to a giant catered lunch from the actor's restaurant Tribeca Grill, according to the New York Post's gossip column Page Six.
A source tells the publication, "De Niro took pictures with the guys, and got a full tour of the firehouse."
It is believed the flames spread through De Niro's home after a clothes dryer ignited.
The Raging Bull star's Manhattan home was damaged by a blaze in June (12) and firefighters initially blamed a build-up of lint in his clothes dryer for the accident.
However, new court papers, obtained by the New York Post, suggest the flames could have been started by a camera or intercom system, and bosses at a security company are preparing to defend themselves over possible legal action.
Executives at Metro Security Communications have filed papers at Manhattan Supreme Court asking for copies of fire department and police calls and incident reports because "it is expected that a property damage action will be initiated by Mr. De Niro".
The company did not install the devices for De Niro, but recently reprogrammed the system.
