A student in Dundee has been frightened to discover that a mystery doppelganger has spent two years recreating her social media posts, according to her sister.

In a Facebook post Linzi Cowan said the lookalike has re-enacted the poses, outfits, and even captions posted by her sister Chloe Cowan on Instagram.

She said the mystery user has even acted out by video, scenes from photographs of Chloe and her father, who has since passed away.

The post was shared 11,000 times before being deleted this afternoon.

Police Scotland told MailOnline they could not confirm whether the incident had been reported to them either in Dundee or elsewhere.

It is unclear who the Instagram user is or what her motivation may be.

Chloe's sister Linzi posted about the strange online behaviour by Chloe's supposed doppelganger saying she wanted to warn people of the 'dangers of social media'.

Her Facebook post read: 'Don't even know where to start with this but just want to let people know the dangers of social media.

'My sister Chloe is at Dundee university and another girl living in Dundee (who my sister wasn't aware of until this week) has been reenacting her life on instagram for almost 2 years.

'This girls stalking behaviour is to the extreme of reenacting videos of a photo album that Chloe posted of my dad who past away (gives me the shivers when I think about it).

'This girl doesn't follow my sister on social media and had made a fake account to stalk her without her knowing.

These near-identical black bikini photos of Chloe (left) and her copycat (right) share the same caption: "Mirror Mirror on the wall, who's the saddest to be leaving of them all!"

After Chloe (left) posted this photo to show off a new accessory, the mystery user uploaded a picture which was similar in pose and caption

'Her behaviour is not ok and I just wanted this out in the open for people to be aware of just how scary social media can be.

'My sister should not have to hide away in worry of her every move being stalked by another girl! Imitation is flattering but this is just too far!'

Linzi shared a series of photos comparing the original Instagram posts by Chloe with those by the copycat.

In one, Chloe is posing in a little black dress, sporting Mickey Mouse ears and holding a cane.

Chloe Cowan posted this photo of herself in a garden in May, only for the other user, honeybasra18xo to copy it at the Glasgow Botanical Gardens just two months later

Chloe Cowan also posted this snap, left, only for the user to copy it. The Instagram account also inverts her own comments below, also using the same emojis

Cowan, left, posted she was 'not feelin (sic) so fresh this morn (sic), only for the mysterious user to copy her pose and write a similar message, right

In the replica her lookalike not only copies the ears and cane and wears a similar dress, she also poses in the same left-foot-forward pose and even used the same caption: 'social life wua can't see you', including the 'poo' emoji used by Chloe in the original.

Another picture from Chloe shows her wearing black jeans and open-toed shoes, with a cropped black top.

She is leaning to her right with her elbow out and her right hand up to the side of her head. The copycat replicates the outfit and the pose with eerie accuracy - adding an almost-identical caption.

Linzi's Facebook post was shared more than 11,000 times after she posted it yesterday, but was deleted at around 3.30pm today after coming to national media attention.

The copycat Instagram account, 'honeybasra18xo', has also been deleted.

Police Scotland in Dundee told MailOnline they had no record of any crime having been reported but believed the woman was resident in Glasgow.

Police in Glasgow could not confirm whether this incident had been reported to them.
