Tributes have poured in for a Greater Manchester Police Special Constable who has died in a horror smash.

SC Samantha Derbyshire, 23, was killed after being hit by a HGV on the M61 in the early hours of Monday.

She was hit after getting out of her car to assess damage following a collision with the central reservation barrier at around 3.30am between junction 4 for Farnworth and junction 5 for Westhoughton.

SC Derbyshire had only been working with GMP Specials since January last year.

Officers manning the MP Specials Twitter account posted: "It’s with deep regret we announce the death of Samantha Derbyshire.

"Sam joined us on January 14, 2015 and worked in the Bolton division.

"Our thoughts go out to her family, friends and colleagues at this difficult time."
