Police visited the premises between 16:00 hours and 18:00 hours on Monday but were blocked from a thorough search after lawyers representing the party discovered the search warrant was defective.
A huge team of police officers returned to the UPND secretariat around 05:00 AM on Tuesday to complete their mission, this time with another search warrant.
The search started around 08:00 hours and was called off after mid-day with the cops finding nothing to incriminate the opposition political party.
UPND leader Hakainde Hichilema’s advisor Douglas Syakalima accused the police of trying to intimidate the opposition but warned that no amount of threats from the PF government will cow them into submission.
“The PF over-lied during the campaigns and that is why each time HH speaks about their promises, they want to stop him,” he charged.
Syakalima said there was nothing seditious at the UPND secretariat that would warrant President Michael Sata sending a battalion to victimise its members.
