Increased protests have led to fears of an escalation of violence at a UK fracking site.
Both demonstrators and unconventional oil and gas firm Cuadrilla are concerned that someone will be seriously as tensions escalate at the site in Lancashire.
Permission for the scheme to drill up to four wells and frack for shale gas at Preston New Road, Fylde, was turned down by Lancashire County Council, but given the go-ahead last October by Communities Secretary Sajid Javid following an appeal.
The move by the Government was welcomed by business groups but provoked an angry reaction from environmentalists and local campaigners, who said it went against the wishes of residents and threatened the environment.
Campaigners have been clashing with police over the weekend.
One piece of footage appeared to show a man in a wheelchair being pushed over by officers trying to move him out of harm’s way.
The use of a lock on tube which ties two protestors together by their arms and makes them harder to move has been condemned by police.
Fylde Police, who have been policing the site near Preston put a statement online.
It said: “On the 4th July 2017 an incident occurred outside the shale gas extraction site on Preston New Road, Blackpool.
“During this incident a 31 year old male states he was assaulted by security staff from site. This incident has been widely reported on social media.
As a result of this, a statement of complaint was received by police and further enquiries have taken place.
“On 17th July 2017 a 28 year old male was interviewed under caution by officers regarding this and other matters.
“As a result of this the male has been reported for summons and a file will be sent to the Crown Prosecution Service.”
When David Cameron was prime minister, he said the Government was going “all out for shale” to boost the economy, jobs and energy security – and soon after Theresa May took over as PM, she launched a consultation which could see homeowners receive individual payments for fracking wells drilled nearby.
But the process – in which liquid is pumped deep underground at high pressure to fracture shale rock and release gas – remains highly controversial, with many protesters turning out for the public inquiry into two schemes in Lancashire.
Opponents of fracking fear it can cause earthquakes, pollute water, lead to damaging development in the countryside and hit house prices, and is not compatible with targets to cut the use of fossil fuels to tackle climate change.
