NYPD spokesman Peter Donald said on Thursday that the department is "closely monitoring" the situation in Barcelona, where the van rammed into a crowd in a popular tourist section of the city.
Donald said the NYPD has also beefed up security around Spanish diplomatic spots in the city.
Authorities say the Barcelona attack killed more than a dozen people and injured scores of others. They were investigating it as an act of terror.
The precautions come at a time when the department had taken extra security measures around Trump Tower for the president's visit there this week.
