A Hoboken resident jumped into the Hudson River around 4:40 p.m. on Saturday, after saying he was upset about the recent death of his mother, according police.

The man jumped in the river from the area of 499 Sinatra Dr., police said.

As police arrived at the scene, the 37-year-old man sat on the ledge and told police they shouldn't come closer to him or he'd jump in, police said. The Hoboken Fire Department also arrived at the scene and tried to approach the man, police said.

The man jumped in the river and swam away further from the walkway when the fire department threw him a rope to be helped out of the river, police said. At that time the firefighters were unable to rescue the man out of the water, according to the report.

Because of the strong currents of the river, the man got stuck under the soccer field at Frank Sinatra Park, police said. The men held on to the wooden poles under the park there, police said. 

At that point a fire fighter in scuba gear jumped in the river too and rescued the man, police said.

The operation took about 40 minutes, police said, and a crowd of approximately 200 people gathered along the walkway at Sinatra Drive.

The New York City Harbo Patrol, Hoboken Police, Stevens Universtiy Police and the Hoboken Fire Department were all present on the scene.

The last time somebody jumped in the river was during Hurricane Irene in August.
