The 77-year-old said she was lonely after losing her parents during lockdown and the end of a long-term relationship. She started speaking to people online and met the person she knows as Alla Morgan in a chat group.
She was told this person was working on an oil rig in the North Sea and was asked to buy Steam gift cards to allow them to keep talking. These cards are typically used for buying video games. The person Nikki was chatting to told her she needed them to allow her to get an internet connection on the rig so that they could keep talking.
Nikki said she was sceptical, but was persuaded to buy several hundred pounds worth of the cards.
She repeatedly asked Alla Morgan for a live video call which was refused, or didn't work. It was then that she started receiving recorded video messages.
"I had started to think, are you a real person?" Nikki said.
"Then she sent me a video to say 'Hi Nikki, I am not a scammer, I am on my oil rig', and I was totally convinced by it.
"A few weeks later she sent me another video, also on the oil rig with bad weather in the background. This was before she started asking me for all this money. "
