Family of unarmed New York man who died after police chokehold meets with US attorney

The family of an unarmed black man who died after being placed in a chokehold by a white New York police officer has asked federal prosecutors to investigate.

The wife and mother of Eric Garner and the Rev. Al Sharpton met privately with U.S. Attorney Loretta Lynch on Thursday in Brooklyn.

Garner died last month when police arrested him on suspicion of selling loose cigarettes on Staten Island. The medical examiner ruled his death a homicide caused by a chokehold, which is banned under police policy.

The police commissioner has promised to retrain officers.

The Staten Island district attorney says he'll present evidence to a grand jury to determine whether any officers will face criminal charges.

Sharpton and others are organizing a march on Saturday. He says he expects a turnout of at least 3,000 people.
