A total of 13 people have now been arrested over the shooting dead of a man as he parked his car on his driveway in Merseyside.

Seven people were arrested in June on suspicion of conspiracy to commit murder.
Six more people have been arrested in connection with his death, Merseyside Police said.
Those arrested earlier include a 45-year-old man suspected of conspiracy to murder as well as three men and two women held over matters including fraud, as well as drug possession and cultivation.
All have been released on bail pending further inquiries.
The four men and two women, aged between 21 and 53, arrested in June have also been released on bail.
Mr Osu was a currency trader and held a pilot's licence.
Merseyside Police described the shooting as a targeted attack.
