Police said Tuesday the women were detained at Liverpool's John Lennon airport "on suspicion of failing to give notification of death" of a 91-year-old man.
The BBC and other British media reported that the women placed the man, a relative of theirs, into a wheelchair and covered his face with sunglasses in a bid to get him aboard a flight to Berlin.
The women, aged 41 and 66, were detained Saturday and have been released on bail. They have not been charged and police say inquiries are continuing.
