A cyclist from India, who is taking part in a 24,140km (15,000 mile) round-the-world challenge, was left without his bike while travelling through the UK, the BBC reported.
Yogesh Alekari has travelled through more than 17 countries in Asia and Europe since starting his journey in Mumbai on May 1.
The 33-year-old said his KTM 390 Adventure motorbike was stolen - along with most of his belongings - while it was parked in Wollaton Park in Nottingham at around 11am on Thursday.
He told thousands of followers on social media that the theft was “painful“ and left him “heartbroken“.
Before the theft, he had travelled through Iran, Nepal, China, Kazakhstan and Uzbekistan, coming to Europe, visiting numerous countries including Germany, Belgium, the Netherlands and France.
The man had planned to continue his journey in the hope of passing through Africa, but the theft thwarted his plans.
“I was in Nottingham for a motorbike event and was going to head to Oxford,“ said Alecari. “I stopped and parked my motorbike in Wollaton Park. I locked it. It was a busy area with children playing, so I thought it was a safe place. I crossed the road and went to get breakfast, but an hour later I came back and it was all gone.
A video taken by a visitor to the park shows Alecari's motorbike driving away, surrounded by two scooters.
The traveller, who has more than 180,000 followers on Instagram and almost 16,000 on Facebook, said the value of the stolen items was more than £15,000.
He said the storage boxes on his motorbike contained his MacBook laptop, a spare mobile phone, two cameras, cash and other items including his passport and clothes.
Alecari said he bought the motorbike in April before he set off on his journey and has since spent £20,000.
„I was completely "shocked," he added. "I just broke down and cried when I realised what had happened."
"My motorbike was stolen, but it wasn't just a motorbike - it was my home, my dream, everything to me as a traveller."
"How could this happen? I've suddenly lost everything."
Alecari said he called the police shortly after his motorbike was stolen, but added that no one had been able to visit the park, which is run by Nottingham City Council.
"They said they would call me and I waited in the park but they never did."
"My dream is to cycle around the world. I've spent a lot of money to get here and I don't want to stop now.
„I've travelled from India to here and passed through places like Iran and Turkey that people said weren't safe - but I felt safe there.
„People had warned me about the UK but I thought I was far from London and Nottingham would be fine.
„I've never experienced anything like it anywhere else.“
Nottinghamshire Police said teams had carried out “local enquiries“ but had so far been unable to find the motorbike.
Sgt Daniel Sheasby encouraged anyone with information to contact police.
