Unforgotten fans in tears as Sanjeev Bhaskar reveals heartbreaking secret note left in Sunny’s rucksack during finale

UNFORGOTTEN fans have been left in tears after Sanjeev Bhaskar revealed a heartbreaking secret note left in his rucksack during the series four finale.

Sanjeev, 57, plays DI Sunny Khan in the hit ITV drama, which concluded last night in devastating fashion.

Viewers were left heartbroken after Sunny's colleague DCI Cassie Stuart died after being involved in a car accident.

Their pain was made even worse after Sanjeev revealed on Twitter that Nicola Walker, who plays Cassie, had packed his character's famous backpack, which never leaves his side.

Sharing a picture of the rucksack, the note and a framed picture of Nicola, he wrote: "Thank you all for carrying us through series 4 of @UnforgottenTV.

"The last of this series #sunnysbackpack was unbeknownst to me, packed by #NicolaWalker - with a note she wrote, when I opened it on set. I cracked."

The note was from Cassie to Sunny and it read: "Dear Sunny, I love you, you know. It's worth saying sometimes. Cassie x."

This set many fans off again with one writing: "Oh you're killing me - set me off again - I'd only just stopped enough to be able to see. I think I need to go watch something humorous now to change my mood. Another fantastic series."

Another tweeted: "I’d just pulled myself together" alongside a crying emoji.

A third added: "Ok now I really am broken! Cracking series, Sanjeev. It’s such a jewel on our telly. Loved the perfect marriage proposal x."

Last week's episode of the gritty ITV drama ended with Cassie getting into a car accident, and last night's finale revealed the injuries were more severe than initially thought.

Cassie's father and son, Adam, were stunned by the news - and Sunny paid emotional tribute to his workmate in the series' final moments as he visited her grave.
