Closed-circuit television images of two people who allegedly used a stolen credit card in Christchurch have gone viral online.
More than 4400 people have shared the online post by April Marx, who says her handbag and credit card were stolen last week.
About $2500 was taken from her credit card in eight transactions between 3am and 5am on Friday. The handbag and its contents were worth about $1500.
Writing online, Marx said she was looking for "vigilante justice" and asked people to share it so the two people in the images could be identified.
She alleged that at least $800 worth of cigarettes were bought with the credit card in one transaction.
The people who used the card bypassed her PIN and forged her signature, she said.
Marx said yesterday that her online tactic had yielded some results.
"I have got a solid name and have passed it on to the police," she said.
"I'm really humbled you all cared enough to share it, thank you all so much."
A police spokesman said the theft was reported to them on Friday.
Marx had since contacted the police to provide details on the use of the cards and possible suspects.
CCTV footage had been provided to police, the spokesman said.
Marx, who works as a sales representative for More FM, said today that the handbag was stolen from her locked car, which was parked in the drive of her home.
She realised her credit card had been taken when Westpac contacted her to say it had been blocked because of unusual transactions.
It was likely the charges would be reversed, she said.
She was provided CCTV footage by a service station so she could give it to police.
When police gave it back to her she assumed they were too busy to investigate, so she decided to put it online and ask for the public's help.
"I didn't expect it to go so big," Marx said.
"I couldn't believe how many people cared about it. People seemed to be really annoyed about people stealing and how blatant they were."
