BROOKLYN - Police are warning Brooklyn residents about a phone scam involving wire transfers.

According to authorities, scammers are calling people and saying that their loved ones are in trouble, and that they need to wire money in order to help.

In one case, cops say a 78-year-old woman was called by a man who claimed to be a police officer and told her to send $1,500 in bail money for her grandson.

The elderly woman sent the requested funds to David's Check Cashing on Sutter Avenue in East New York where it was picked up by a woman.
