Royal Malaysia Police Inspector General Mohamad Fuzi Harun said the vehicle was awaiting the killers, and that they later escaped to another country in the region. The Malaysian police was reportedly investigating whether they had escaped to Thailand.
The Malaysian chief of police added that weapons that may have been used in the hit were sent to a forensics laboratory, clarifying it was still unclear whether they were indeed used in the killing.
"Police have exposed the weapon," he said, "but I cannot yet divulge more details until a report on the matter is received."
Lastly, Harun revealed that the assassins used fake passports from Serbia and Montenegro to enter Malaysia, adding passports of other countries may have also been used.
Albatsh, 35 at the time of his death, was shot to death April 21 at around 6am by two unknown assailants riding a motorcycle, as he was making his way from his Kuala Lumpur home to a nearby mosque.
The engineer, originally from the Jabalia refugee camp in the Gaza Strip, worked at the isolated enclave's electricity company before leaving for Malaysia. He received his bachelor's degree from the Islamic University of Gaza, and a doctorate from a Malaysian university after moving to the country in 2011.
He was considered outstanding in the field of electrical engineering and has won numerous awards for his work. According to his résumé, he had worked in areas that may relate to installing transmitters on drones.
He was buried in Gaza on April 26. "Albatsh had always hoped for a martyr's death," Gaza leader Ismail Haniyeh said at his funeral. "We shall sever the arm that was sent to rid of this knowledge."
"Albatsh returned to Gaza in spite of the opposition of (Defense Minister Avigdor) Lieberman. We thank Malaysia, Egypt and anyone who helped in returning him to Gaza," he added.
