An eyewitness described the incident as ‘ten minutes of extreme terror’
A pair of moped drivers broke into a cafe and threatened customers that they were told not to drive through a low traffic neighborhood area.
A dozen police officers reached the spot at 10.40 am on Sunday.
The two men initially tried to drive through an LTN zone, which was stopped by planters by Calton Avenue when told by a customer.
When the drivers started shouting and making threats, frightened passers-by and children took shelter inside the shop.
The drivers then pushed their way inside and took everyone to the back of the shop, one threatening that he had a carving knife.
Café director Roger Wilkinson, 66, was fixing some panels outside when he saw the nightmare unfold.
“It was ten minutes of utter horror,” he told Evening.
“In the middle of Dulwich on a Sunday morning, you just don’t expect it.
“It all started with the LTN zone. A man was there reading the newspaper with coffee and I saw two men abusing and shouting at him on the bike.
“They had apparently tried to stop them from going into the area between the two sets of planters. He told them that they were bad and they couldn’t do it.
Mr Wilkinson warned drivers to “back off and go the long way” when they turn him over and get more verbal abuse.
He continued: “One of them was riding, kicking things, knocking cables, and moving people out of the way.
“Then he picked up the chairs outside the cafe and threw them at the window. Luckily they are laminated glass and they just bounced.
“For about a minute, they pushed their way in and I thought they would dodge til and break the place. He said ‘everybody behind the shop.’
“We had a 16-year-old working there, he was afraid of children.
“The tall man appeared to behead one of the customers, who may have just been dodging.”
Officers arrived within a few minutes but people had fled from the spot. It is said that a man’s leg slipped when he got off the car.
Mr Wilkinson described the two men as white, “hyper” and “out for violence” in their behavior.
According to the director of the cafe, the planters are vandalized with widespread opposition to LTN.
“It is an ongoing battle for a year, but this is the closest it has inevitably come for ABH. It was just awful,” he said.
The Metropolitan Police confirmed that officers were called to reports of two men acting aggressively on Calton Avenue on October 10.
A spokesman said: “It was reported that the men had broken into a window of the business premises and assaulted a man. One person suffered minor injuries.
“The officials participated and conducted a thorough search of the area. There was no trace of the suspects. Inquiries are on to trace them.”
