A 16-year-old boy has been arrested on suspicion of stabbing a Saudi student and a father-of-five to death in Essex.
One of his alleged victims was stabbed more than 100 times, while the other was attacked as she walked to the University of Essex campus.
The teenager, who has not been named, was arrested on the Salary Brook Trail in Colchester on Tuesday.
That is the same path where Nahid Almanea, a student from Saudi Arabia, was stabbed to death on 17 June last year.
Wearing a traditional abaya and hijab, the 31-year-old was walking from her student accommodation in nearby Woodrow Way to the university complex in Wivenhoe.
She died of stab wounds after being attacked at around 10.40am.
Hundreds of people attended Ms Almanea's funeral in Saudi Arabia and officials from the country visited Essex for a briefing on the murder case last month.
Months earlier, 33-year-old James Attfield was killed in a different part of Colchester.
The father, known as Jim, was found on Riverside Path in the early hours of 29 March with more than 100 stab wounds.
The teenager was arrested on Tuesday on suspicion of possessing an offensive weapon but after two days of investigation by the Kent and Essex Serious Crime Directorate, he was re-arrested in connection to the murders.
The boy is in custody at Colchester police station and officers continue to appeal for information.
Anyone who can help with the investigation is asked to contact Essex Police on 101 or Crimestoppers anonymously on 0800 555 111.Reuse content
