Detectives investigating the disappearance of 32-year-old Lorraine Cox from Exeter have arrested a further two men on suspicion of murder.
Six men, aged between 22 and 71, are now in police custody in connection with the incident.
Magistrates have granted officers a further 36 hours to question the suspects.
Lorraine was last seen in the city centre in early hours of Tuesday, September 1, and was reported missing on Thursday, September 3.
A Devon and Cornwall Police spokesperson said today (Friday, September 11): “Detectives investigating the disappearance of 32-year-old Lorraine Cox have made two further arrests.
“Six men have now been arrested in connection with the incident.
“A 43-year-old local man and a 22-year-old local man have been arrested on suspicion of murder and are in police custody.
“Four other men aged 22, 30, 33 and 71, all arrested on suspicion of murder, remain in police custody.
“Detectives have been granted a further 36 hours to question suspects after a request by police was approved by magistrates.
“The family of Lorraine have been kept informed of the updates.”
Detective Chief Inspector Lee Nattrass, from the Major Crime Investigation Team, said earlier this week: “Lorraine Cox had initially been treated as a missing person following concerns for her welfare from her friends and relatives.
“However, following a significant development in the case, we are now treating this as a murder investigation.
“Extensive searches by specialist officers are currently taking place in and around Mary Arches Street in Exeter City Centre.
“A cordon remains in place and the public are likely to see police activity ongoing in the area for the next few days.
“We would like to hear from anyone who believes they had seen or heard from Lorraine since 1 September as a matter of urgency.
“If you have any information that can assist us with our investigation, please contact the police on 999 quoting log 285 for 9 September.
“The family of Ms Cox have been informed of this development and are being supported by trained liaison officers at this difficult time. They ask for their privacy to be respected.”
