Two people have been stopped from entering a ward where a teenager shot by the Taliban is being treated.
The pair - described by police as "well-wishers" - turned up at Birmingham's Queen Elizabeth Hospital overnight and made efforts to see Malala Yusufzai, 14, who arrived in the UK for treatment on Monday.
At first a hospital spokesman said he understood arrests had been made after people claiming to be family members tried to gain access.
But West Midlands Police later clarified that the two individuals posed no threat to the Pakistani schoolgirl.
A police spokesman said: "They were stopped in a public area of the hospital and questioned by police, who recorded their details and advised the pair that they would not be allowed to see her.
"No arrests were made and at no point was there any threat to Malala."
The hospital's medical director Dr Dave Rosser said earlier that the hospital and police are "very comfortable" with security arrangements at the hospital.
Referring to the incident overnight, Dr Rosser said: "We don't believe there's any sort of threat to her personal security - we think it's probably people being over-curious."
Malala was shot on a bus in front of her friends last Tuesday after campaigning for the right to go to school.
She was saved by neurosurgeons in a Pakistani military hospital and has since been in intensive care.
Dr Rosser said medics in Birmingham have been "very pleased" with the teenager's progress and that she had a "comfortable" first night in the UK.
He added she has been showing "every sign of being just every bit as strong as we've been led to believe that she is".
Experts at the hospital were beginning to plan for reconstructive surgery, he added.
