Manchester/England - A week ago would have been the 136th birthday of one of the most terrible dictators in history - Adolf Hitler. Some neo-Nazis took this as an opportunity to celebrate - complete with swastika cake, flags and a "Führer" soccer shirt.

This dubious celebration took place in Manchester , UK .

As The Sun reported, the group gathered in a pub and brought decorations consisting of flags with a swastika, SS runes and the Iron Cross.

The pub said it only found out about the event the following day and immediately informed the police .

After the party, the right-wing extremists shared a post in their Telegram group: "On a beautiful sunny afternoon in Greater Manchester, a group from the Northwest British Movement got together to celebrate Uncle A's 136th birthday."

The British Movement is a neo-Nazi organization founded in 1968, known for its long history and links to violence and extremism.

As Manchester Evening News further reports, photos of the questionable celebration were also shared on the Telegram channel, including one that showed the cake with a prominent swastika in the middle.

A man making the Hitler salute was also wearing a German national team jersey with the words "Führer 44".

A spokesman for the pub said the group had entered the pub under the pretext of celebrating a birthday.

"The group actively concealed their clothing and activities during their visit so that their actions were not visible to staff at the time. (...) Let's be clear: We are absolutely appalled by what happened. We do not tolerate this behavior and these individuals are not welcome in any of our establishments," the pub said.

The police announced in a statement that they had begun an investigation and were asking for information about the incident.
