I'm writing this with tears in my eyes, I came down here to London England for a  short vacation unfortunately i was mugged at the park of the hotel where i stayed,all  cash,credit card and cell were stolen off me but luckily for me i still have my passports with me. I've been to the embassy and the Police here but they're not helping issues at all and my flight  leaves in less than 3hrs from now but am having problems settling the hotel bills and the hotel  manager won't let me leave until i settle the bills,I'm freaked out at the moment.Got nothing left with me..i was mugged off all i got,can you please help me out with some cash?So freaked out here
