A British mother alleged to have abandoned her baby in Portugal could face extradition proceedings to face charges there.
Police in the UK say they will not press charges against Katherine Penny, 23, from Basingstoke in Hampshire.
But the Portuguese authorities are still considering whether to make an extradition order for her.
Katherine Penny - will not face charges in Britain
And a Portuguese judge has said it is unlikely the baby will be returned to the UK.
The three-month-old baby, named Charles, was found abandoned in a pushchair in the town of Albufeira, near Faro airport, on Sunday morning.
Miss Penny and her partner Mark Beddoes had gone voluntarily to Bournemouth police station on Tuesday asking to talk to officers about their son.
Miss Penny was arrested over unconnected "minor motoring offences", a Dorset police spokesman said.
No obligation to return
Detective Sergeant Neil Claughton said neither Mr Beddoes, 29, nor Miss Penny were under any obligation to return to police concerning the alleged abandonment.
"The child protection office spoke to the woman who gave an account of events in Portugal. In relation to these events she is under no obligation to return to Bournemouth police station," he said.
He went on to say that the force had liaised with the child protection unit, the Criminal Prosecution Service, the National Criminal Intelligence Service and Interpol as well as the Portuguese authorities.
The BBC's Jane O'Brien said: "The alleged offence does not appear to warrant the British authorities taking out a prosecution as opposed to her (the mother) being sent back to Portugal."
Duped claim
Under Portuguese law the maximum penalty for abandoning a child is eight years in prison.
Mr Beddoes, from Bournemouth, has reportedly said that he was duped by his partner into believing that the baby was being put into care in Portugal.
But the boy was only taken to a care home after being found abandoned on Sunday.
Mr Beddoes is also said to have denied being the baby's father.
Mark Beddoes: Has promised to return to Portugal
Portuguese police said the couple lived in the Algarve resort and worked in the timeshare industry.
Mr Beddoes has said he only left the child because the couple were desperate for money, and has promised to return to Portugal as soon as he had saved enough.
His friend Paul Green told BBC Radio 4's Today programme that Mr Beddoes had suggested the couple go to the police.
The baby's grandfather, Mike Penny, has asked for privacy for the family to deal with the situation.
"I fully understand the human interest in the events that have unfolded in the last few days regarding the welfare of my daughter's child," he said.
Cleft lip
"However, I need to be clear that this is a private family matter where the needs of the child are paramount."
The baby, born at the hospital on 2 October, was recognised by a nurse because of a distinctive cleft upper lip, he said.
Captain Edmundo Emilio, a police spokesman in Faro, said the baby was taken to hospital but did not need treatment.
Any extradition order could take months to process.
Baby Charles was on Wednesday night described as "well" as he continued to be looked after in a Portuguese orphanage under the care of the local court, the Foreign Office said.
