Police have been criticised for setting up cameras to catch speeding cyclists and motorists while failing to stop armed robbery in Richmond Park.
The complaints came after three cyclists were attacked in or around Richmond Park in the past six days, by gangs on mopeds wearing balaclavas and armed with machetes.
Billy Martin said he had seen police set up speed traps in the park, all the while the violent incidents were not being stopped.
'Looks like a permanent deterrent presence is required', he added.
Two cyclists were attacked in Richmond Park in consecutive days last week, and had their bikes stolen, before Mark Radville was rammed off his bike outside the Roehampton Gates on Monday.
Simon Balfre asked the Royal Parks Police why there were only two officers per shift covering the whole of Richmond Park and Bushy Park.
Campaign group, The Department of Parks and Recreation, which states it is fighting 'to reclaim The Royal Parks from motorists' also questioned the police on why it took 42 hours to make people aware a cyclist had been attacked by bike-jackers when, over the weekend, the public were notified about a crash involving two cyclists soon after it happened.
In response, Royal Parks Police said it does not have a dedicated social media team, and 'it depends who is on duty at the time' for what gets posted.
Mr Radville, speaking after the attack on Monday afternoon, said he thought he was going to be 'decapitated in the street'.
The 37-year-old was riding his £5,500 bike outside Richmond Park when he noticed two men wearing balaclavas on a moped were following him.
The attack on Mr Radville, is the latest in a string of incidents inside and around Richmond Park in the last few days
They caught up alongside him with one of the men flashing the blade before the keen cyclist was rammed off his bike and thrown to the ground.
One of the riders picked up the bicycle and flung it over his shoulder before jumping onto the back of the moped and the two thieves rode off.
Mr Radville, a mobile-coffee shop owner from Lewisham, suffered cuts and bruises in the fall and spent hours in hospital following the incident at about 5pm outside The Alton Primary School, in Danebury Avenue.
It was the third similar incident to have occurred near or in Richmond Park since Wednesday.
He told MailOnline: 'I was cycling along when I noticed a moped behind me over my right shoulder.
'They then pulled up alongside me and one of them showed me a machete - he only pulled it out slightly but showed it to me.
'At that moment I change gear and go for it, trying to get away as fast as I can. Then he pulls it out completely and it looked like he was going to go for me.
'I went up onto the pavement to avoid them, but then I'm running out of pavement so I went back onto the road and that's when they rammed into me, just outside the school.
'The guy got off the moped and was still waving his machete about as he didn't want anyone to get near him. He picked up my bike and jumped onto the back of the moped with my bike over his shoulder.
'One minute I was cycling along, and the next minute I thought I was going to be decapitated in the street. It was terrifying.'
The suspected thieves were photographed scarpering off the scene holding a bike - which Mr Radville said was his - on their shoulders.
Campaign group, The Department of Parks and Recreation, which states it is fighting 'to reclaim The Royal Parks from motorists' tweeted the two pictures.
Mr Radville, who cycles about 350km a week, was cycling from Lewisham to Richmond Park and had intended to ride to Box Hill and back to Lewisham before the incident.
He described it as being 'like a terrorist attack' and said the machete was about 'a foot and a half long including the handle'.
A spokesman for the Metropolitan Police told MailOnline: 'Police were called at 17:09hrs on 11 October to High Street SW15 after a man was reported to have been assaulted by two males who then stole his bicycle.
'One of the suspects was reported to be in possession of a machete and so armed officers responded.
'An area search was conducted, however the suspects could not be traced.
'The victim was taken to hospital as a precaution but was not seriously injured.'
Police confirmed no arrests have been made and said enquiries are 'ongoing'.
Despite this incident happening outside Roehampton Gate The Department of Parks and Recreation renewed calls for the gates to the park to be closed to motorists.
They tweeted: 'The news that this latest attack occurred just outside the park, does not alter our demand that the gates be shut to protect park users while these criminals are at large.
'We know these
