Police have arrested a 28-year-old man on suspicion of murder following the death of 65-year-old Montserrat Martorell Elias in Derry during a 'horrific attack'. Her body was discovered in a ground-floor flat on Harvey Street after firefighters responded to reports of a fire on August 24. Detective Chief Inspector Anthony Kelly stated that the victim suffered multiple injuries, and a postmortem examination is pending to determine the cause of death. The police are actively seeking witnesses, particularly a man seen in the area around the time of the incident, and have increased patrols to reassure the community. Authorities are appealing for anyone with information, especially those who may have relevant CCTV footage, to come forward. The investigation is ongoing, and police have urged the public to refrain from speculative discussions that could hinder judicial proceedings.
