Football fans will pay their respects to the two constables killed in the head-on crash on the A66 and other Cleveland Police officers as the force continues to investigate a spate of incidents in the area.

Middlesbrough FC has asked supporters to pay tribute to Pc Matthew Blades and Pc Tom Clough before their 12.30pm home game against West Bromwich Albion on Saturday.

Pc Blades, 37, and Pc Clough, 38, died in the collision with a Volkswagen Passat travelling the wrong way on the A66 at South Bank last weekend.

The King has also written to their families to express his condolences, the Mirror reported.

Middlesbrough FC said in a statement: “Immediately before kick-off, we’re asking supporters to join us in paying respects to Pc Matthew Blades and Pc Tom Clough, the two Cleveland police officers who tragically lost their lives in the line of duty last weekend.

“We are also showing our appreciation for the dedication and hard work of both men, and to Cleveland police force in protecting and supporting our local community.

“The commitment shown by officers and staff, often in challenging and demanding circumstances, plays a vital role in keeping residents safe and helping people feel secure in their homes, neighbourhoods and local areas.”

Cole Worthy, 17; Theo Rae, 17; Makai Saddington, 18; and 23-year-olds Michael Cahill and Jakub Matusiak were also killed in the crash.

Cleveland Police said its officers have been tackling alleged organised crime in the wake of the crash and, on Friday night, said some 24 people had been arrested in the crackdown.

Officers said four men, aged 35, 25, 40 and 21, were being held on suspicion of criminal damage with intent to endanger life after a vehicle crashed into a house in Steele Crescent, Middlesbrough, on Thursday morning.

They were also being questioned over alleged arson after a caravan was set alight in Atlee Road on Wednesday morning, and a drugs offence.

The force said the men were in a vehicle when they were stopped by police on Kingsley Road in Grangetown on Thursday night.

Earlier on Friday, detectives confirmed they were not linking a house fire which killed a seven-year-old girl and her aunt to the A66 crash.

Natalie McDonald, 34, and her niece, Valentina Foster, died while four other people were injured in the blaze on Wednesday morning – with two men, aged 23 and 31, still in custody on suspicion of murder.

Hundreds of extra police officers have been drafted in to support officers after the series of recent incidents in the Middlesbrough and County Durham area.

The Police and Crime Commissioner (PCC) for Cleveland said the past week had been “the most tragic” in the area’s history as he thanked officers for their hard work, but stressed “the outdated and ineffective funding system” for policing “disadvantages” his force.

Matt Storey said: “My thoughts remain with the family, friends and colleagues of Pc Matthew Blades and Pc Tom Clough. They will be remembered as selfless, professional and courageous police officers, dedicated to serving their communities.

“I also offer my sincere condolences to everyone affected by the horrific fire in Grangetown, which sadly resulted in the deaths of two people.”

He said he met the policing minister on Friday, adding: “I have reiterated my request for a better, long-term, funding deal to enhance Cleveland’s response to serious and organised crime.

“People in Cleveland have the right to live without the fear of crime and I understand the concern, anger and grief recent events have caused.

“I want to assure them that I will continue to fight for the funding needed to improve Cleveland Police’s ability to prevent crime, bring offenders to justice and keep our communities safe.”
