The St Thomas police have detained a suspect in Monday's double murder of two brothers from Bath in the parish.
The man, whose identification is being withheld pending further investigations, was picked up yesterday.
The bullet-riddled bodies of Leo Martin, 28, and Anthony Hunter, 26, were found along the Bath main road. Investigators are linking the deaths to a domestic dispute.
This is contrary to the belief of residents, who told police of an ongoing feud between thugs from Bath and Deacon, a neighbouring area.
"We have one person in custody for questioning ... We believe the murders were linked to an ongoing domestic feud and not to a feud against rival gangs," said Superintendent Jonathan Morrison, head of the St Thomas police.
