"We are using all our available means — visible and unseen — to find the suspect in this stabbing as soon as possible," police said in a statement, as they appealed again for witnesses.
That included studying video footage from the area, where many surveillance cameras are located.
The attack in the Netherlands came hours after a man wearing a fake explosive vest stabbed several people in London, killing two, before he was fatally shot by officers. Police are treating it as a terrorist attack.
Dutch police say the motive for the stabbing in The Hague remains unknown. "We are keeping all scenarios open," their statement said.
The stabbing occurred around 7:45 p.m. in an area teeming with shoppers and close to the city's most popular nightlife centers.
Police cordoned off the area until deep into the night as forensics experts combed the street for clues.
The street was opened again Saturday.
