Two men have now been charged with the murder of Dilip Unadkat in his Wembley flat.
Ahmed Mahnoud El-Shubrawy, 26, from Perivale, is accused of stabbing the shop manager to death along with 36-year-old Sami Mahmoud Salama.
Police found Mr Unadkat dead in his flat in Empire Way at the end of November.
El-Shubrawy, a plasterer from Egypt, was arrested before Christmas after an appeal by police to try to trace him.
He will face the charge at the Old Bailey on March 20 along with Salama.
Both men have been remanded in custody.
