Arthur Labinjo-Hughes (4 January 2014 – 17 June 2020) was a six-year-old child living in the West Midlands, England who was abused and subsequently killed by his parents during the COVID-19 pandemic.

In February 2019, Labinjo-Halcrow stabbed her new partner, Gary Cunningham, to death after a period of mutual domestic violence.

However, the child's uncle noted that Thomas Hughes seemed to be becoming stricter with the boy, and Arthur appeared to be more fearful of getting into trouble.

[8] In early 2020, Thomas Hughes took his son to multiple medical appointments but the boy was not diagnosed with any mental health problems.

[3] Though Thomas Hughes' mother asked that he and Arthur come to her house, he refused,[8] instead deciding to move in with Tustin at her home in Solihull for the duration of the lockdown.

While he was at his grandparents' house, Arthur said that he had been pinned against the wall by Tustin, called a "horrible ugly brat", and his grandmother found several bruises on his back.

Thomas Hughes said that Tustin coached the boys to lie about the incident and had warned him they would lose custody of their children if he did not cooperate as well.

By the end of the month, Arthur was moved out of Tustin's son and daughter's bedroom and made to sleep on the living room floor.

The camera also recorded the couple and Tustin's children enjoying food and leisure activities which Arthur was not allowed to participate in.

[8] On the morning of 16 June, Arthur appeared on CCTV footage to be weak, in visible pain and struggling to lift his bedclothes.

The child was secretly given a drink of water by the hairdresser's partner, who later described him as "gaunt", "malnourished" and "a poor little kid who was broken".

[8] At the time of his death, a medical review found that he was covered in 130 bruises, that he had been poisoned with salt, and that the extent of his injuries were compared to torture.

[16] The head of Solihull council reported that social workers had been forced to leave their homes due to abuse and threats related to the case.

Several parallels were noted between the cases such as both children being killed by their parent's new partner, having extended family who tried to help them, and being of known concern to the authorities.

announced an annual pre-season game named "The Arthur Cup", with a portion of proceeds from the match going to the NSPCC.

[23][24] Due to the nature of Arthur's injuries and the accounts given by Tustin and Thomas Hughes, both were arrested on the evening of 16 June initially on suspicion of assault and then murder.

[25][13] Police officers examined hundreds of videos, audio files and photos found on Tustin's and Hughes' mobile phones, and analysed thousands of messages they sent each other.

[13] Emma Tustin was convicted of murdering Arthur Labinjo-Hughes at Coventry Crown Court in December 2021, and was given a life sentence with a minimum of 29 years.

[33][34] The review found that child protection services had been involved in Arthur's life on various occasions dating back to 2018 and repeatedly not intervened to help him.
