Skins star Kathryn Prescott is in a critical condition and "lucky to be alive" after being hit by a cement truck in New York.

The news of Kathryn's accident was broken by her twin sister Megan on social media.

The pair are best known for playing twins Emily and Katie Fitch in the 2009 E4 drama.

Megan told fans on Twitter her sister was was lucky to be alive after the incident, which happened on Tuesday September 7, and following surgery, the actress is now in a serious condition.

Megan also shared an urgent message asking for help as she looks to get over the US to see her sister.

She told fans: “I received the most terrifying phone call I’ve ever received in my life on Tuesday evening.

"My twin sister Kathryn was hit by a cement truck while crossing a road in New York on the 7th September,”

“After fighting through complex surgery some of Kathryn’s injuries include: broken pelvis in two places, both of her legs, her foot and her left hand,” Megan wrote, adding that her twin “narrowly avoided paralysis”.

“The doctors are hopeful that she will make a full recovery but this will only be possible with the correct care right now.

“She is alone in New York with no family members. I need help getting to New York to support her recovery. I will have to help her until she can start to walk again,” Megan stated.

Due to the ongoing Covid-19 pandemic, any non-US citizens are unable to fly directly into the country, and Megan has asked her followers for help in trying to reunite with her sister.

“I need to be there to help her with literally everything as she will be able to do incredibly little by herself.

"She will be in rehab for a very long time and will need 24/hr care even after she leaves the hospital,” she said.

Sadly, she applied to the US Embassy for exemption from the current restrictions and was denied.

“I am devastated. I am double vaccinated, I had a PCR test yesterday and can fly at the drop of a hat. I have documents from the hospital confirming the extent of Kathryn’s injuries and am willing to do anything to get to her as soon as humanly possible,” Megan continued.

She encouraged her followers to share her post, as she tried to find a way to appeal the US Embassy’s decision.

“I don’t know what to do with myself. I have to be able to get to my sister to care for her and right now I have no way of doing so,” the heartbroken former actress wrote.

“I don’t want her to go through this alone,” Megan added.

Kathryn and Megan are best known for playing twins in Skins in 2009, alongside Jack O’Connell, Kaya Scodelario, and Luke Pasqualino.

Kathryn went on to star in TV shows such as Finding Carter, and 24: Legacy, as well as appearing in the 2019 flick A Dog's Journey.
