Sussex Police has launched a murder investigation after a woman was found dead in a house in Fiveways this morning (October 26).
Police said officers were called to a house in Sandgate Road, Brighton, just after 6am, where a woman, aged 46, had sustained multiple stab wounds and was pronounced dead at the scene.
Detective Chief Inspector Till Sanderson, from the Surrey and Sussex Major Crime Team, leading the investigation, said: "A 51-year-old man from Seaford has been arrested on suspicion of murder.
"We would like to hear from anyone who saw or heard anything suspicious in or around Sandgate Road between 6pm on Wednesday and 6am on Thursday.
"It appears that both suspect and victim were known to each other and we are not currently seeking anyone else in connection with the incident."
Sussex Police said enquiries began after a man in his fifties called police from outside the city's John Street police station shortly after 6am, and that information he provided led police to Sandgate Road.
The scene was sealed off and officers began house-to-house enquiries. People living nearby were also questioned as they set off for work.
Anyone with information about the incident is asked to contact police online or call 101 quoting Operation Navan.
Alternatively, contact Crimestoppers anonymously on 0800 555 111.
The arrested man remained in police custody on Thursday afternoon, police said.
