The suspect, who was apprehended in southern Sweden, is to be taken to Dalarna on Tuesday. The girl has not been found.
“A 42-year-old man was arrested at 5.45pm on Monday in Rasta at Hallandsåsen,” said police spokesman Torsten Persson.
Police would not reveal why the man has been arrested.
The suspect has a previous conviction for a rape in northern Sweden, Aftonbladet reports.
Police forensic experts have been conducting a search of the man’s truck, which is not yet completed.
“But we know there isn’t a body in the front or the hold,” Tony Andersson, head of forensics with the police in Kristianstad, told Aftonbladet.
Police have seized a tachograph, a mobile phone and a laptop computer.
Engla Höglund had been to football training in Stjärnsund and left her teammates to cycle the five kilometres home around 2pm on Saturday afternoon. She never turned up and her bike was found 500 metres from her home in the small town in northern central Sweden.
The 10-year-old called her mum on her mobile phone as she was leaving training just before 2pm.
They spoke several times as she cycled home and their last conversation took place as Engla was close to Rönnösund near Klarängarna. When Engla’s mother tried to contact her 30 minutes later, there was no answer.
A massive search began soon thereafter.
