The sharp-dressed suspect wanted for fatally stabbing a 66-year-old man in Hell’s Kitchen turned himself in to police, authorities said.

The 28-year-old man walked into the NYPD substation in Times Square shortly after midnight Wednesday and told police, “You need to arrest me. I have the knife in my pocket,” according to sources.

Cops then searched the man and found two knives in his coat pocket.

The man was then cuffed and was taken in for questioning. His identity has not been released and charges against him are pending, officials said.

The suspect is believed to have stabbed Timothy Caughman several times in the chest and back when the two got into a fight near the corner of Ninth Avenue and West 36th Street around 11:30 p.m. Monday.

Caughman, who had 11 prior arrests, staggered around the corner to the Midtown South Precinct looking for help. He died hours later after being rushed to a nearby hospital.
