Two men wanted over a fatal shooting outside a boxing event in Kensington last Friday night have been arrested in Sydney.

Police have confirmed 27-year-old Abdullah El Nasher and 25-year-old Mikhael Myko were arrested by NSW Police in Bankstown about 9.45pm on Friday.

The two fugitives were believed to be hiding out in an apartment in Bankstown when members of the Tactical Operations Unit arrived at the apartment block and a dramatic arrest unfolded.

Abdullah El Nasher jumped from a balcony to a lower floor in an attempt to escape police and was treated by NSW Ambulance paramedics before being taken to Liverpool Hospital. On release, he will be charged with a Victorian arrest warrant for murder.
