Police reveal how they tracked down Nasen Saadi after he stabbed two women on a Bournemouth beach.

Nasen Saadi was described in court as a "social misfit" who committed his crimes "to feel powerful".

Jack Saunders attacked Anthony Jacob after being challenged over damaging a parked van.

Amie Gray was stabbed in the heart and left for dead by Nasen Saadi in Bournemouth last May.

Police arrested Nasen Saadi at his home in Croydon a few days after the attack.

Amie Gray's wife Sian exclusively tells the BBC: "She didn't die on that beach, she still lives on."

Nasen Saadi told police "that's not me" after seeing CCTV footage from the night of the attack.

Nasen Saadi walked up and down the promenade before stepping on to the sand and attacking the women.
