A 37-year-old Lithuanian national, who was arrested on Monday, has been charged with the murders of Indian-origin Avtar Singh Kolar and and his wife Carole Kolar in Birmingham last week.
The West Midlands Police said that the suspect, named Rimvydas Liorancas, will appear before the magistrate in Birmingham on Friday morning.
The bodies of Avtar Singh, 62, and Carlole, 59, were found by their police officer son, Jason, from their house last Wednesday in Handsworth Wood, Birmingham.
Of the other two people detained in connection with the murders, a 41-year-old man has been released without charge, and a 24-year-old man is on bail.
The police said that forensic post-mortem examinations have been conducted, which confirmed that both the deceased died as a result of blunt force trauma to the head.
Both had been struck a number of times.
