Two further arrests have been made in connection with a double stabbing during a cannabis factory robbery in Brierley Hill last Thursday.
The two men killed were 19-year-old Khuzaimah Douglas from the Moseley area of Birmingham, and 36-year-old Waseem Ramzan who lived in Pensnett Road.
A 46-year-old was arrested yesterday (23rd February) from a property in Stoke-on-Trent and will be questioned by detectives today.
A 42-year-old was also arrested from the property on suspicion of assisting an offender and has been released on police bail.
Officers say the men were killed during a robbery of a cannabis farm which spilled out onto the street.
Two men, aged 23 and 21 who were arrested in Holyhead Port in Wales, on Saturday (22nd February) on conspiracy to rob have been released on police bail while enquiries continue.
Officers are appealing for anyone who was in the area in the time and witnessed the disorder to get in contact with them.
They say they are particularly keen to hear from drivers who were in the area and may have recorded the disorder through their dash cam footage.
