2. Any peace officer of another state of the United States, who enters this state in close pursuit and continues within this state in such close pursuit of a person in order to arrest him, shall have the same authority to arrest and hold in custody such person on the ground that he has committed a crime in another state which is a crime under the laws of the state of New York, as police officers of this state have to arrest and hold in custody a person on the ground that he has committed a crime in this state.
