Sanchez’s former flame Michelle Carvalho was caught up in a violent mugging after a shopping trip with her friend.

The model, who claims to have given the Manchester United ace his pet dog Humber, shared footage of the horrifying attack to her Instagram page.

Michelle and her female friend were targeted as they made their way back to an apartment in Providencia, Chile.

The pair were approached by a man wearing a pink t-shirt that offered to help them with their shopping trolley.

But the supposed Good Samaritan tried to snatch Michelle’s pal’s bag and make a run for it.

Sanchez’s former lover jumped to the defence of her friend as she tried to beat the man with a broomstick.

Alongside the video on social media, she wrote: “My friend has just been mugged at the door of a building in Providencia.

“The man in a pink top came up to us and offered to help us with a shopping trolley.

“We accepted and the next second he grabbed my friend’s bag and dragged her back out to the pavement, managing to make off with her mobile.

“I hit him a few times.

“The worst thing was that there were four men nearby but none of them helped and they just stood there looking.

“We’ve already reported the crime to the police.

“My advice is ‘Be careful and don’t accept help from strangers’.”

Michelle was first pictured with ex-Arsenal star Sanchez in 2012, but prefers to keep tight-lipped about their relationship.

Speaking amid reports in 2016, she said: “I try not to speak too much because he doesn’t like it and I don’t like to be identified as the woman who went out with Alexis Sanchez.

“It was something that happened, but I don’t like to be remembering it all the time.”

And she denied that she gave Sanchez both of his beloved Golden Retrievers, named Atom and Humber.

She said: “Both no, just Humber. I gifted Humber to him.”

Sanchez, who has failed to impress on loan at Inter Milan, trained shirtless with his pet pooches during the coronavirus lockdown.
