A woman took to Twitter to seek help after she boarded a taxi and no one has heard from her after her last tweet.
In the tweet, the woman said she boarded a "one-chance" taxi in Kaduna and she and other passengers were being driven to a "dark place".
"Please, I need help," she added.
Her tweet has generated concern, with Twitter users calling on the authorities to find a way to locate the lady, since she hasn't posted anything else after her last tweet was shared at about 12am today, May 5.
