The two men, aged 25 and 27, were arrested on Thursday and
Friday and are Polish nationals.
"We are sure that it is them who committed this crime, we have
proof," Andrzej Borowiak, a police spokesman in Poznan in western
Poland, told AFP.
In all, three vehicles were stolen on Monday night at
Hoppegarten in eastern Germany. Police later found one van
belonging to a building firm.
Police were searching Sunday for the other vehicles including
the van that was supposed to take the bodies to a crematorium in
Meissen in Saxony, eastern Germany.
Two other people are also being sought. A reward of 5,000 zlotys
(1,300 euros) has been offered for information leading to the
arrest.
"Everything suggests that the vehicles are on Polish soil,"
Borowiak said.
A Protestant pastor in Berlin has called on the thieves to
return the bodies.
"Please, think how you would feel if you could not bury your
mother or your father," Markus Droege said in an appeal reported by
German newspapers.
