Mwafulirwa said at the time of the raid, the commissioner and his family were not at the house and the family was unable to access the house now.
He said police provided security at the house but the protesters outnumbered them to cause the damage and loot property.
Mgawi is the first MEC commissioner to be attacked since MEC came under fire over presidential results of the May 21 poll. He became MEC commissioner on the ticket of MCP. Other commissioners come from the DPP and UDF, who all were appointed by President Arthur Peter Mutharika following recommendations from their respective parties.
Lilongwe and Mzuzu have been the epicentres of ugly demonstrations engineered by the Human Rights Defenders Coalition (HRDC) and supported by the opposition MCP and UTM seeking to force the resignation of MEC Chairperson Justice Jane Ansah.
