'Super Junior' Leader 'Leeteuk' was robbed in Switzerland over the weekend, which resulted in the loss of some of his valuables including his passport. 'Leeteuk' informed his fans of the unfortunate incident in his Instagram post, which has since been deleted.

'Leeteuk', who heads the phenomenal Korean boy band who shot to fame with such hits as “Sorry, Sorry”, “Mr. Simple”, and “Superman”, was in the European country to shoot a new television program entitled 'Delivery'. The location of the incident was not disclosed. Reports have it that 'Leeteuk', or Park Jeong Su, 33, and his crew lost their computers, mobile phones, and other personal effects after the robbers smashed the window of the vehicle where their valuables were placed.

Police are still investigating the incident.

In another Instagram post, he warned that tourists to be extra careful when traveling outside their home countries. Even as Switzerland is deemed generally safe, he cautioned that security measures should nonetheless be taken to prevent similar incidents. He delivered the message at the request of the Embassy of the Republic of South Korea in Switzerland.

Not the first time in Switzerland

It was not 'Leeteuk's first Time In Switzerland. In 2015, he shot a reality show, 'The Friends in Switzerland', with fellow 'Super Junior' member, 'Ryeowook'. They were shown exploring some of the famous sites of the Swiss capital, Bern, as well as suburban Switzerland.

For their assistance in promoting tourism in Switzerland, the Swiss Tourism Board even named 'Leeteuk', 'Ryeowook' and another 'Super Junior' member, 'Kyuhyun', Travel Ambassadors for 2015.

Thus, it was ironic for the 'Super Junior' front man, who actively endorsed Switzerland tourism, to have been victimized by the serious crime.

The 'Delivery' cast and crew have sought the help of the Korean Embassy for the issuance of their lost passports so they can return to Seoul.

Super Junior preparing for its awaited comeback

With five of the 11 members of 'Super Junior' serving in the military, the group has been on a temporary hiatus. 'Leeteuk' himself has been busy with hosting stints, including many variety shows such as 'I Can See Your Voice' and 'Idol Party'.

However, with the discharge of 'Siwon', 'Eunhyuk' and 'Donghae', 'Super Junior' is expected to stage a comeback in the second half of the year. They have opened an Instagram account in preparation for their return to active promotions but unfortunately, there were calls to exclude 'Sungmin' in their comeback. Another member, 'Kangin', has also been on the sidelines after figuring in a drunk driving incident last year.

Members were also recently spotted meeting supposedly in preparation for their much-anticipated return. 'Super Junior's last world tour was the 'Super Show 6', which was anchored on 'Mamacita', the group's seventh studio album.
