Two deadly snails were found crawling along a busy London street.
Two deadly snails were crawling along a London street
The giant African land snails - which can carry killer parasites - had been dumped at a bus stop in a lettuce-filled cardboard box but escaped and were spotted gliding along the pavement.
Jamie-Lee McEvoy, who saw the creatures near London Bridge railway station, told The Sun newspaper: "They were the size of my arms.
"I thought I was seeing things. Everyone was wondering where they'd come from. But no one knew what to do or wanted to touch them."
The molluscs pose a serious health danger to humans as they have rat lungworm - which triggers deadly meningitis - but they were collected by wildlife volunteer Beth Crivelli.
She said: "They would have died crawling along the streets in the heat.
"They're living with me in a proper sealed box until I can find someone to adopt them."
