Flytippers caused an inferno when 40 tyres were set alight on South Tyneside allotments
The blaze at Holder House Allotments, in South Shields, was the third incident in which fly-tipped items has been set on fire in the borough in the space of a month.
A spokesman for Tyne and Wear Fire and Rescue Service said its crews were called to the latest incident in Holder House Way at 8.33pm on Tuesday.
Firefighters found in excess of 40 tyres on fire along with a small amount of rubbish.
A witness described police car s and fire engines on the scene as the area was sealed off and searched with police dogs.
The blaze, which was put out by 9pm, comes after rubbish was dumped and set alight in a South Tyneside park on August 29.
The waste - described as car parts - was left near to Cleadon Park bowling club.
A witness said a lorry had been seen being driven onto the site before the rubbish was discarded and set on fire. It is the second incident to have happened within 24 hours.
The previous night firefighters were called to Sunniside Lane in Cleadon at around 9pm after a large number of tyres were dumped and set alight.
Coun Moira Smith, Lead Member for Area Management and Community Safety, at South Tyneside Council, said: "This type of illegal activity is simply outrageous.
“Dumping waste and then setting it on fire poses serious risks to nearby properties as well as causing damage to this popular and well-loved community asset which is so valued by some of our most vulnerable residents.
“Dealing with fly tipping costs the Council around £2million a year at a time when our resources are already stretched.
"This irresponsible behaviour of a tiny minority simply adds to the burden of law-abiding Council Tax payers.
“We will do everything in our power to bring the perpetrators to justice and would urge the public to report any suspicious activity they may have seen.
"We are particularly keen to get details of the vehicles used to transport the materials and would appeal to any residents who have CCTV in these areas to check their footage.”
