Hong Kong protesters create Lennon Walls in opposition to extradition bill

July 11 (UPI) -- Inspired by the Beatles singer, so-called Lennon Walls have become lightning rods for conflict between Hong Kong protesters and police as the fight over an extradition bill continued this week.

Two former police officers and at least two other men have been arrested and accused of assault at Lennon Walls across the island. Hong Kong has suspended the controversial extradition bill, which would allow criminal defendants to be sent to mainland China for trial, and declared it "dead." But protesters are calling for the bill to be completely withdrawn.

Opponents of the extradition bill have been posting sticky notes on walls as a form of protest -- inspired by the wall in Prague, Czech Republic, that's covered in graffiti influenced by Beatles singer and guitarist John Lennon.

One man was filmed punching another in front of a Lennon Wall Wednesday night. The attack went viral on social media.

One protest drew more than 200 people at one point.

In one incident, protesters were arranging the sticky notes when supporters of the extradition bill showed up and tried to remove the messages. Several scuffles ensued.

Hong Kong has its own judiciary and a separate legal system from China and there's growing fear that the extradition bill weakens that separation.

Hundreds of thousands of demonstrators who are opposed to a proposed Hong Kong law allowing extraditions to China protested in the streets. The violent clashes between demonstrators and police left at least 54 people seeking treatment, hospital officials said. At least two were in serious condition, but most were discharged.

The extradition bill would have allowed for fugitives from Beijing's courts residing in Hong Kong to be extradited to China. The bill was put on hold Saturday, but then 2 million people took to the streets Sunday, demanding the bill be permanently scrapped. Photo by Stephen Shaver/UPI | License Photo

The former British colony has been allowed its own local institutions under a "one country, two systems" arrangement with China. Protesters see the extradition law as a further whittling away of the island's democracy by Beijing. Supporters say it will prevent the island from being a haven for Chinese criminals.

In 2047, Hong Kong fully becomes part of China because that is when the "one country, two systems" deal ends. Hong Kong was a British colony until 1997 when the United Kingdom worked out a deal to turn Hong Kong to China under the stipulation that Hong Kong residents would continue to enjoy many of the rights that they had as British subjects.
