A 22-year-old man has been arrested and bailed over the fatal stabbing of teenager Mustafa Momand, Sussex Police said.
Armin Mehdikhani-Sarvejahani, 16, was jailed for life at Lewes Crown Court on Thursday for Mustafa’s murder.

After the sentencing, Sussex Police said a man had been arrested on suspicion of conspiracy to murder in relation to Mustafa’s death.
A spokesperson said: “As part of the wider investigation into Mustafa’s murder, on April 25, a 22-year-old man from Saltdean was arrested on suspicion of conspiracy to murder.
“He has been released on conditional bail while inquiries continue.”
