People are being asked not to put their lives at risk by jumping into or swimming in the River Thames to cool off on hot days.

The warning comes after incidences of people congregating on the banks of the river and jumping into the Thames, particularly in the Teddington area.

Many are thought to have been drinking alcohol.

Today Richmond Council, the local police and fire brigade said they are "becoming very concerned about the situation."

Parents urged to warn children

Cllr Gareth Roberts, leader of the council, said: "Some parts of the Thames are very deep and bodies of water stay cold whatever the weather. It is very easy to get into trouble and drown.

"People who have been drinking lose their inhibitions and decide to swim in the river against their better judgement.

"Please talk to your children and tell them not to be tempted to cool off during the warm weather, it is extremely dangerous and they should avoid it at all costs.

"Also, actions like this put huge pressure on the emergency services who are extremely stretched already due to the Covid-19 pandemic."

Neighbourhoods Chief Inspector Nick Hackett-Peacock, from Richmond Police, added that they were asking people to think twice before spending the day by the river.

"Last weekend we received numerous reports of overcrowding and antisocial behaviour," he said.

"We are still in a pandemic and appropriate social distancing measures should be taken.

"We also do not tolerate anti-social behaviour and will enforce a dispersal zone if proportionate and necessary.

"Therefore, please be sensible. Don't enter the water and be respectful of others," he said.

A 48-hour dispersal zone was put in place last weekend, covering much of Richmond town centre and giving extra powers to police officers and PCSOs.

'Never drink and swim'

John Snelgrove, from London Fire Brigade, also warned against the risk of cold water shock from jumping in the river.

He said: "It causes panic, anxiety, disorientation and loss of muscular control, which cause you to gasp for air and as a result, inhale water.

"We would also urge people never to drink alcohol and then go swimming, or attempt to jump into water.

"You should avoid walking or running near water on your own or late at night as it's easier than you think to slip and fall in.

"We're not trying to scaremonger or spoil people's enjoyment of the summer – but there is a very real risk when it comes to London's canals, waterways and the Thames."
