US star Sean Kingston has warned Twitter followers about US reports that sharks had been spotted swimming in flood waters following Hurrican Sandy.
The singer was among a number of stars sending thoughts to friends and fans caught up in the extreme weather that has so far claimed the lives of 13 people in New York - but his good wishes came with added bite.
"Heard somebody seen a shark just swimming in there neighborhood.. because of#Hurricanesandy this is crazy stay safe people!" Kingston tweeted, (sic).
A photo of a shark swimming in a front yard in New Jersey has been seen online - although many believe it to be a fake. It is not believed that there are any sharks swimming in the waters that have hit New York.
New York city has shut down to the severe weather conditions - with power being turned off across the city.
The above image, shared on Twitter, was reportedly taken in New Jersey
