Emmerdale fans were left sickened on Wednesday evening after tuning into the ITV soap.
Noah Dingle (Jack Downham) took his obsession with Chloe Harris to the extreme as he stole her keys and broke into the house where she lives.
The teenager was seen snooping around Chloe's bedroom and went straight for her underwear drawer and rifled through her knickers.
He then started taking pictures of her bedroom, using his mobile phone, before making himself comfortable on her bed.
Noah then jumped up and hid in the wardrobe as he heard Chloe (Jessie Elland) downstairs after she managed to get in via the back door.
Luckily for him, Kerry called Chloe just as she was about to put something away in her wardrobe, so she didn't find Noah hiding.
Later on in the episode, Noah was seen listening in to Chloe and Kerry having a conversation as it was revealed he had bugged her bedroom.
Viewers tuning in at home couldn't believe their eyes at his behaviour and took to Twitter to comment.
One person said: "I appreciate it's an important storyline (and for their sake, it had better be handled appropriately) but Noah makes me feel physically sick # Emmerdale."
Another tweeted: "What a creep Noah is. #Emmerdale," while a third added: "i literally have no words for noah #emmerdale."
Someone else posted: "Nah this is beyond disgusting, I wish chloe had seen him. Tracking her phone then putting a camera in her room, come on Noah WHAT IS WRONG WITH YOU??? #Emmerdale."
And another viewer said: "Got a bad feeling about this creepy Noah storyline #emmerdale."
ITV spoilers recently confirmed that Chloe and Noah take centre stage during Emmerdale's special flashforward week, as she finally uncovers he's been stalking her.
Getting a hold of his laptop, she finds evidence including photos and video footage that proves what Noah has been up to, leaving her shocked and fearing for her safety.
Chloe is in Noah's house when she makes the discovery, and realises the danger she could be in so tries to leave.
But Noah soon turns nasty with her and tries to stop her escaping, just as someone walks in and watches the horror unfolding.
