Newspaper headlines: 'Cuffed, drugged and stuffed in a bag'
A model from south London, who is said to have been kidnapped in Italy by a man who threatened to sell her to the highest bidder on the dark web, is widely quoted describing what happened.
It's the lead story in the Sun and is also reported in the Mirror, the Times, the Telegraph and the Mail.
Chloe Ayling describes being abducted and waking up handcuffed in a suitcase in the boot of a car.
She says she feared for her life "second by second, minute by minute, hour by hour".
The Black Death Group is suspected of being behind the apparent kidnapping.
The Times says the group is either "one of the most dangerous criminal gangs in the world, or the depraved fantasy of people who rarely leave their keyboards".
The Times also reports how the father of Justin Gatlin - the sprinter who beat Usain Bolt to win the 100m final at the world championships - has called on British fans to lay off his son.
Gatlin - who has twice been suspended for failed drugs tests - was booed as he accepted his gold medal at the London Stadium on Sunday.
Willie Gatlin says his son has not committed a crime and that the people who booed him should read the official reports on his case.
But the Daily Telegraph's Paul Hayward believes Gatlin plays the system with a "poor me" routine.
Writing in the Daily Mail, Matt Lawton says Gatlin's gold will ultimately be good for athletics - by forcing the sport to confront the problem of doping.
He says anti-doping agencies lack the power and funding to tackle what he calls a "global disease" and that "the sport of athletics got what it deserved on Saturday night".
The Daily Mirror says it is an "outrage" that Gatlin was allowed to compete and that any athlete convicted of doping should face a lifetime ban.
The Guardian carries warnings of a postcode lottery in IVF treatment.
The paper says NHS commissioning groups in 13 areas of England have restricted or stopped offering IVF since the start of the year in an effort to save money.
National guidelines recommend that women aged under the age of 40 should be offered three cycles of IVF if they have been trying to conceive for two years.
The Guardian quotes one of the pioneers of the technique, Professor Simon Fishel, as saying that people across the country should be treated equally - and that only a tiny fraction of those who need the treatment have access to it.
The Financial Times reports that Wandsworth Council in London has seized more than 130 rental bicycles, describing them as a "yellow bike plague" cluttering up pavements.
The "oBike" has been launched as a rival to Transport for London's bike scheme and users can pick up and leave the bicycles anywhere, unlocking them with a smartphone app.
The council has accused oBike of dumping thousands of bikes on London's streets without any warning. oBike says it is "disappointed" with the council's response.
And finally, men's make-up counters are likely to appear in chemists' shops and department stores within five years, according to the UK boss of L'Oreal.
Vismay Sharma has told the Daily Telegraph that demand for make-up is growing fast among men of what he calls "the selfie generation".
The paper says that, last week, the online retailer, ASOS, launched a male-only make-up range which includes a concealer, beard and brow filler, and mascara.
