BROOKLYN, N.Y. - A tourist is recovering after being grazed by a bullet during a shooting at a Brooklyn subway station this week.

Police say a woman visiting from Iowa was standing on the "4" train platform at Franklin Avenue in Crown Heights Tuesday night, when a man fired a shot across the train tracks.

She was grazed in the ankle.

Police believe it might have been related to a shooting that started minutes earlier.

"It may have stemmed from an incident topside that led down below. We had a Shot Spotter response approximately 10 minutes before that indicating six shots fired as we look into that area. And now the question probably more than likely will turn to gangs. We see a couple of incidents leading up to it in the weeks before of possible shots fired," said NYPD Chief of Detectives Dermot Shea.

The woman was standing with family members on the platform.

No one else was injured.
