Detectives in Mpeketoni, Lamu seized more than 70 suspected stolen mobile phones, laptops and tablets in an ongoing crackdown on suspicious phone repair stalls.
Four suspects were also arrested.
This is aimed at combating the electronic theft surge in the area.
Police in the operation said they also recovered assorted M-Kopa mobile phones, flashing tools and hard drives.
The operation was staged following complaints there was a surge in the theft of mobile phones.
The gadgets are usually reconfigured at local repair shops and sent to other parts of the country or neighbouring countries where they are resold.
An analysis of some of those recovered has revealed the victims were violently robbed of the gadgets, police say.
An investigation is ongoing to get those behind the same.
This is the latest such operation to be conducted aimed at addressing the crime.
Such operations have been conducted in Kisii and Nairobi where up to 500 mobile phones have been recovered.
Police have warned second-hand mobile phone dealers and the electronic engineers or repairers handling the gadgets they will face serious charges when investigations are completed.

She said detectives are now pursuing good leads on the issue and they aim to address the menace.
Dr Onyango encouraged those whose gadgets are stolen to always report the same to police.
