A large police presence responded Friday to a home on Webster Avenue in Harrison.
Harrison and Westchester County police, including a SWAT team and hostage negotiators, descended on a brown house with an American and Paraguayan flag flying in the front yard.
Paramedics took someone from the house into an ambulance, but authorities have not yet released information on what happened.
Some people who were seen leaving the house did not comment.
This is a developing story. It will be updated.
