Stuff lost from the cabin baggage
 

Hi,

I was travelling from San Francisco to Mumbai via Newark on , because of the space constraint (Newark to Mumbai flight) crew member requested my cabin baggage to shift to the check in baggage, where I mentioned them that the bag does not have any locks they assured that there will not be any issues because of this. After reaching home I found that my IPhone, Ladies watch and some cash was missing, could you please help me to find out the same.
