Kampala Central MP Muhammad Nsereko is right now being transferred to Tororo in eastern Uganda, where he might be charged over his statements relating to the death of Butaleja Woman MP Cerinah Nebanda.
However, The Observer understands that Kinkiizi East MP Chris Baryomunsi is most likely to be charged before Buganda Road Magistrate's court.
Some reports say he will be charged shortly but this has not been independently verified.
Kampala Mayor Erias Lukwago, who was travelling to the east with the MP, was forced out of the vehicle by security personnel earlier in the afternoon.
MP Nebanda died suddenly on December 14th and there has been suspicion that she could have been poisoned.
Last week the government released a postmortem report suggesting she died of narcotic drugs, a report that Parliament and the MPs' family have rejected.
On Monday, the government arrested MPs Nsereko and Baryomunsi, who were among the harshest critics of its handling of the MP's death and the eventual report suggesting narcotics as the possible cause of death.
After Nebanda's death, Parliament had engaged an independent pathologist, Dr Sylvester Onzivua, to conduct parallel tests.
But the government stopped Onzivua from travelling to South Africa for toxicological tests and confiscated the body samples. Some MPs have suggested that the government could have had a hand in the death of the outspoken MP.
Sources have told us that MP Nsereko is being taken to Tororo to be charged because he committed the alleged offence in the neighbouring Butaleja district. He was speaking during Nebanda's burial.
Meanwhile, there is heavy deployment of Police and sniffer dogs at the Jinja Bridge over the river Nile, in Tororo, and in Butaleja. It is not clear why the police have deployed heavily along the road, although it may have been in anticipation of unrest.
MP Nsereko's wife is said to be travelling to Tororo, in one of the vehicles forming what is now becoming a Nsereko convoy.
