Security alert over Kate and William's visit to New York

Security is to be stepped up around the Duke and Duchess of Cambridge during an official visit to New York amid widespread demonstrations over the death of an unarmed black man at the hands of local police.

Thousands of protesters have flooded the city's streets after it was revealed officers who killed father of six Eric Garner would not face criminal charges.  

The disruption comes ahead of the Royal couple's three-day tour of the US, during which Prince William will be hosted by President Barack Obama and his wife, Michelle, at the White House.

Tonight it was claimed the couple, who are expecting their second child, will be given extra security by the New York Police Department in light of recent turmoil. 

While an NYPD spokesman declined to comment, they confirmed the Duke and Duchess 'will be getting security.' 

The couple's security team will take extra precautions throughout the visit as tensions continue to flare over the death of an unarmed black man at the hand of a New York police man  

Clashes continue in the city following the decision that officers who shot Mr Garner will not face charges
