POLICE have sent reinforcements to Livingstone and Mpongwe to help maintain law and order ahead of the parliamentary by-elections set for February 28.
Police spokesperson Elizabeth Kanjela said security had been beefed up in the two areas to forestall violence.
Ms Kanjela advised all the political parties to carry out their campaigns in a peaceful manner.
"We are discouraging the use of certain strategies such as the execution of the Mapatizya Formula which is not known by anybody, hence posing a threat to many lives.
"We also discourage the ferrying of cadres from other areas to either Livingstone or Mpongwe where the by-elections will be taking place on February 28," she said.
Ms Kanjela said police would not hesitate to bring to book all those advocating violence either by the use of words or actual physical harm.
"Our officers are on the ground patrolling and carrying out security check-ups to ensure that people are not carrying offensive weapons," she said.
She appealed to the people of Livingstone and Mpongwe to cooperate with police officers and be able to report to the police any one intending to bring about confusion.
The Mpongwe seat fell vacant following the resignation of Gabriel Namulambe from the MMD. He has since been adopted by the Patriotic Front(PF) to stand in the same constituency.
The MMD has adopted Miniver Mtesa, while United Party for National Development(UPND) candidate is Rabson Chilufya.
Reagan Ndlovu is the National Restoration Party (NAREP) candidate, while UNIP has adopted Kenny Kuveya.
In Livingstone, the PF is fielding Lawrence Evans, Regina Musokotwane is standing on the UPND ticket and Fred Siasuntwe on MMD.
Others are Green Mwanang'ombe for UNIP and Angela Ikabongo for the Revolutionary Community Party.
