Both sides presented their arguments to the Uppsala District Court which adjourned to deliberate. It was expected to announce a decision at 4pm.
Swedish deputy director of public prosecutions Eva-Marie Persson said the WikiLeaks founder had not cooperated with the Swedish investigation previously, fleeing from an extradition order, and therefore needed to be detained and questioned in Sweden.
She asked the court to order Assange's detention in his absence, a standard part of Swedish legal procedure if a suspect is outside the country or cannot be located, and which would be the first step to having him extradited.
He was subsequently sentenced to 50 weeks in prison for breaching bail conditions when he took refuge in the embassy.
Following his arrest Swedish authorities reopened a 2010 rape investigation, which had been closed in 2017 with the argument that as Assange could not be reached it was not possible to proceed with the probe.
Legal tug of war
Sweden's prosecution authority did not want to comment on the likelihood of the court granting the request for a detention order.
However, in 2010, when Sweden's then director of public prosecutions Marianne Ny requested Assange's detention from Stockholm's district court, a detention order was issued.
Although at that time the investigation also included three cases of sexual harassment and unlawful coercion, all have since reached their statute of limitations.
If the Uppsala court also grants the prosecutor's request, Eva-Marie Persson has made clear she intends to issue a European Arrest Warrant “concerning surrender to Sweden”.

Such a request will, however, have to compete with an extradition request from the United States, where he is facing a total of 18 charges, most of which relate to obtaining and disseminating classified information over the publishing of military documents and diplomatic cables through the website WikiLeaks.
The decision of whether to extradite him to the United States or Sweden would rest with the UK interior ministry.
On Thursday, a scheduled hearing on the US extradition request in London was pushed forward with chief magistrate Emma Arbuthnot referring to Assange was “not very well”, and stating that the next hearing could be held at Belmarsh prison, where Assange is serving his sentence.

The day before WikiLeaks expressed “grave concerns” over the condition of the organization's founder and said he had been moved to the prison's health ward.
“During the seven weeks in Belmarsh his health has continued to deteriorate and he has dramatically lost weight,” WikiLeaks said in a statement.
Earlier in the week Assange's Swedish lawyer, Per E Samuelson, also unsuccessfully requested the Uppsala District Court to postpone the Swedish hearing, citing difficulties he had preparing the case with his client.
Samuelson told AFP that he had met with Assange in Belmarsh's health ward on May 24th, but had been unable to discuss the case properly since “it was difficult to have a normal conversation with him”.
The United Nations special rapporteur on torture and other cruel, inhuman or degrading treatment, Nils Melzer, on Friday said the drawn-out different legal processes against Assange amounted to “psychological torture”.
