The city’s police tweeted at around 8:30pm on Saturday that they were investigating a “possibly suspicious object”.

Following a two-hour long investigation, the alarm was lifted. No suspicious objects were found, German media including Bild and Der Tagesspiegel reported.

Two men who “left the square suspiciously quickly” have been arrested following Saturday’s events, police said in a briefing at the scene according to Der Tagesspiegel.

No further information was initially released or confirmed about the pair.

Large numbers of armed police were present and the scene was also being investigated by police dogs, according to Berliner Zeitung.

The Christmas market is located close to the Gedächtniskirche church, one of the most recognizable buildings in the German capital.

12 people lost their lives and several others wounded in a terror attack on the Breitscheidplatz market in 2016, when Tunisian Anis Amri drove a lorry into the Christmas market.

Amri was later shot and killed by police in Italy while on the run.

Visitors to the Christmas market left the area in a calm and orderly manner after the alert was raised on Saturday, Berlin’s police wrote on Twitter.

Trains at Zoologischer Garten station were temporarily delayed during the police operation.
