THE family of an architect who died after being viciously assaulted may have to wait "weeks" until the cause of death is established.
Dad-of-three Deepak Abbi received blows to the head during a daylight attack as he tried to stop youths entering his business in Drogheda, Co Louth.
Forensic experts were today carrying out further tests in a bid to determine whether his death was directly linked to the assault.
An initial post-mortem examination was "inconclusive", sources have revealed.
The news comes a day after Mr Abbi's heartbroken daughter, Esha, told the Herald that the family believe gardai know who was behind the assault.
"They know who did it, but they are looking for more witnesses," she said.
Gardai want to speak to anybody who may have been at the junction of Bessexwell lane and Shop Street last Thursday. CCTV footage from the area is also being examined.
It's understood Mr Abbi was shoved against a wall by three 16-year-old teenagers. The three youths fled the scene but it is understood that all have been contacted by gardai.
Mr Abbi told local officers that he was feeling fine and did not wish to lodge a formal complaint. He later died in Beamont Hospital.
