Two people are due in court over an arson attack in Waterford that killed four members of a family.

Philip and Kim English and two of their children, Callum and Jayden, perished in the fire during the early hours of Tuesday morning (October 13). Two other children, believed to be in the same family, remain in critical condition following the fire.

A man in his 20s and a woman in her 30s were arrested on Thursday in connection with the arson attack, and are suspected of carrying out the attack on behalf of an organised crime group.

Both people have since been charged in connection with the attack, and are due before a sitting in Clonmel District Court on Saturday afternoon, at approximately 4:30pm.

The chief suspect was reportedly questioned by Gardaí on Thursday night, after he and his alleged accomplice were suspected of carrying out the petrol-bomb attack.

The pair allegedly have connections to criminal gangs in the Waterford area, and are known to Gardaí.

Philip English and Kim English, and two of their children, Callum and Jayden, were killed in Tuesday's arson attack in Waterford City.

Extra.ie understands that the arrested man had been acting as an enforcer for drug gangs in the area and was actively involved in carrying out drug-related intimidation. The arrested woman was detained by detectives on suspicion of acting as the driver in the shocking attack. Several security sources confirmed the identities of the arrested pair.

‘This man is very well-known to gardaí in the area,’ one senior source explained. ‘He’s a hired hand for several gangs in the area and has a history of carrying out attacks on people who owe drug debts in the city. What you have to remember is that there’s a lot of different drug dealers operating across the city. It’s not like you belong to one gang. It’s all very fluid.’

The couple and their children will have a joint funeral in Waterford on Monday afternoon (October 19).

Their death notice reads that they will be reposing at the Sacred Heart Church Parish Centre, The Folly, Waterford on Sunday, October 18, from 2pm until 5pm.

Requiem Mass for the four will be held in the Sacred Heart Church, The Folly, Waterford at 1pm on Monday afternoon (October 19). Burial afterwards in Killbarry Cemetery.
