Sara Connor and boyfriend handed over to Bali prosecutor

Australian woman Sara Connor and her British boyfriend David Taylor have arrived at the offices of Bali prosecutors over the alleged murder of a local police officer.

Ms Connor and Mr Taylor were transported by tactical vehicles from Denpasar Police Station this morning to the district prosecutors' office.

Denpasar Police Chief Hadi Purnomo said they had been a "little late" in handing the pair over to prosecutors as DNA tests had taken longer than expected to complete.

The pair have been held at the police station since their arrest on August 19 following the discovery of local police man Wayan Sudarsa's bloodied body on Kuta Beach.

Prosecutors last week confirmed Ms Connor and Mr Taylor will face charges over murder, violence causing death and assault causing death.

The pair are expected to be tried separately in court next month.  

Police have alleged the couple went to the popular beach on the night of August 16 where they had been "intimate".

Ms Connor then lost her purse, sparking Mr Taylor to confront Mr Sudarsa about the misplaced item.

A scuffle allegedly ensued in which police said Mr Taylor hit Mr Sudarsa with several items, including a two-way radio and a beer bottle.

They allege Ms Connor also became involved, triggering the police man to bite her on the thigh.

She maintains she was only trying to separate the pair.

Leaving Mr Sudarsa lying motionless on the sand, Connor and Taylor initially went back to their hotel.

In the days following they burnt their clothes and dumped a number of the police officer's personal items, including his mobile phone.
